Hi guys,
The archos addon 3g usb stick doesnt activate when switched on through the control panel? It will only activate if I reboot the tablet but nothing happens when using the quick access settings (control) panel or the regular settings panel. Major drag!
Is it a bug or is there anything I can do about it?
Cheers,
Rick
I'm having the same issue sometimes, sometimes it works.
What might be happening is port itself going bad as Archos seems to have used a flimsy ribbon cable on the 3G port. Since the port can actually move in and out it stresses the ribbon cable and breaks the data traces in it.
See this post over on the Archos Fans website. It has pictures in it showing the ribbon cable in question. It seems the power traces can still deliver power but the data traces are smaller and pretty much get destroyed.
So the port will get power, but not able to send data essentially.

I had this once and sent my 80G9 to Archos to get it repaired. A solution is not to slide the stick out, so the cable is not stressed to much. On the new one I sometimes have the problem that it takes a while to connect to the 3G stick or I need to reboot. But it depends on the firmware aswell.

The internal cable connection is one issue... the hardware design itself and the driver/software is another.
Please have a look at dmesg output if the 3G stick refuses to connect.
There seems to be some trouble to detect devices on the host port in general after a while. A reboot generally fixes these issues.
Might be something with the USB PHY not getting resetted properly or other things after sending the device to sleep...
Anyway as long as the stick works after reboot it's more or less acceptable for me.
Have fun!

I checked the dmsg log after connecting and switching the port on & off. This produces various errors such as 'cannot enumerate device' and 'write error on temp directory' and bunch of other problems which might or might not have anything to do with the issue concerning the secondary cpu boot. It seems the driver had been implemented poorly. The only thing that works consistently is rebooting the device but as soon as it's gone to sleep for a short period, it cannot activate the 3gstick anymore. Please note this is the original Archos 3G stick which cost me an extra 65euro's on top of the 300euro's I spent on the G9....

Hey guys.
Any time I connect the phone to my computer via USB, the phone's touchscreen goes bonkers. It wont register my touch in the correct location, it jumps around and registers button-presses that I never pressed, or won't register a firm screen-press at all!
If the USB is unplugged, everything zips along accurately.
Any idea what might be causing this, and how I might fix it?
Just a quick background:
I rooted and installed the lag-fix. I encountered a problem with the lag-fix, restored factory settings, and root/lag-fixed again. The problem cropped up after the factory restore.

That's wacky. Since you've already done it once, I'd just restore again and see if that fixes it.
Also... not sure if this is a side-effect of the factory restore, but guess what suddenly appeared in my Widgets list??

Using LauncherPro by any chance? It's been showing up with LP since Day 1.. If not, that's pretty darn cool then.

I've since reset the factory settings again; no luck. Still all wonky when USB is plugged in.
I'm considering taking it back to best buy and simply exchanging it for a different one, since I've only had it for a day. I would think that resetting everything to factory defaults would have fixed any software problem. Maybe this is a hardware problem that I just now noticed.
I have heard roomer, that if your usb is to low or to high of a voltage it will bork up the touch screen while plugged in.
it seems a common occurrence on many Android phones that use our style of USB port that if you use a 3rd party usb cable (i.e. one other than what shipped with the phone) as well as many 3rd party usb wall chargers that the touchscreen will either go bonkers or freeze up alltogether.
I've seen the exact same thing happen with my friends HTC MT3G and Motorola CliqXT using certain cables and chargers. Any cables/chargers that do this to my Vibrant do it to their phones too.
Interesting. I'm glad I read all this before I decided to take it back;
the laptop I had it plugged into is so fubar'd, that it would not surprise me to find that it has incorrect voltage...
This happens all the time on my Droid 2, Nexus and Fascinate. I just swipe very quickly and press lightly. However, no matter how many "tricks" I try it's still hard to flip through screens or open the correct app. Hardest task would be to navigate a website. Considering it happens on multiple Android devices and computers I never really put too much thought into it. Just figured it to be a Android bug.
Wow, never seen this. Now I do use the cable that came with my fascinate to plug into my computer, however car charger, wall chargers, and a USB charger (in my truck), I just use the cables from my Droid1. All my chargers are generics... Hmmm..
my htc touch pro 2 did the same thing when i used a gps car charger... screen went crazy
chargers
Ok. So for anyone wanting to know what's going on in the background to cause problems with your phone with crappy chargers....
I first discovered this with another touch screen player *cough*ipodTouch*cough*cough when I was trying to make a universal 4-port USB charging bay that would work with my sansa and my ...other player.
The specification that most device-manufacturing companies use nowadays for charging states that for a device to recognize a charger (and to start accepting a charge from the charger), the data pins must be shorted (connected together). This is what Sandisk, Apple, and several others are using. That is how I built my 4 port USB charger and it works flawlessly (with my sansa, ipod, galaxy, and Cowon S9).
NOW, somewhere floating around on the net are specs that state that some data must be sent/received through the USB's data cable (i believe it claims to need any 2.5V) which basically puts some resistors in to make a voltage divider.with the power and ground and data pins. THESE ARE BAD SPECS. They might have been legit in the past for some other device, but they are NOT what our phones need.
So some of the cheap, off-brand chargers are actually sending random messages to our Phones through the data pins (non-sense 2.5 volts). I haven't heard any reports of this damaging the phone or mp3 players yet, but whenever I plug mine into a charger and I lose the ability to control the screen, I get nervous b/c I know there is voltage on the data pins, and I don't know if it's the correct amount. So I get nervous
...does that make sense?
I had the Droid and the first time I saw that, it freaked me out. It seems to be an issue with touch screen android phones when they don't receive the correct voltage, whether because of a 3rd party cable, or a different computer voltage or something. I was using my blackberry mini usb charger and it would act like it had rabies. Nothing is wrong with your phone.
The charger included is plugged in next to my bed, and I'm using my Droid's USB cable in the computer without issues. That's very strange. I've never heard of this problem.

Sorry dude. It's not just android handsets, and it doesn't (seem) to have anything to do with the proper voltage. I've taken multimeters to the chargers. They are providing the proper ~4.5-5V range. It has to be the data pins.
Although, that's just the chargers I've had. Take a voltmeter to your usb chargers (don't touch the casing at the same time!) and see what their voltage is. But a low voltage just wouldn't charge your phone, and a high voltage would damage it.
Guys, I'm convinced the usb connector on my 9 month old TP is defective and gets worse each time I use it. I had bought a touchstone charger to ease the connector wear but still, I was eventually having problems with USB data connectivity using store bought cables. I even sent my TP in to fix the connector and when I got it back, still no USB connectivity. Just a completely wiped TP. So HP sent me one of their "genuine" silver dot cables and low and behold it worked fine. (My original cable was lost)
Now, months later, I'm having problems with the USB data connection again. I either get the "Not enough current message" in WebOS or no MTP USB symbol in CM9. Sometimes the PC will chime positively but with an error message (can't detect device). I received another genuine HP cable and it behaves the same as the other one. Inserting them normally, they appear to be in tight, the PC will chime but Windows will say that there's a problem, can't detect device. The only way to get it to work is to insert the microusb side at a 45 degree angle tilted downward and hold it in for 5 seconds, then (ever so slowly) release the pressure to the connector. 50% of the time I'll get a Windows message that says the USB is degraded and run slower than normal (which I think means it thinks its in USB1.1 slow xfer mode) and 50% it works fine at USB 2.0 (until I pull the cable out of the connector). I also have 2 store bought cables that won't ever successfully connect to USB with the TP but work fine with my Samsung cell in both charging and xferring music over to the phone.
So what I'm getting at here is that no standard microusb cable is the same and that there must be something special about the HP genuine one. Do these cables have a resistor on pin 4 ID tied to GND pin 5? Even so, I think what is wearing the most is pins 1 & 2 and maybe 3 (VCC and the data pins) which is why it may only work by concentrating on seating those pins first. Does it make sense that the 'can't detect device' message comes up with just the data lines and ground connected but no VCC? For that matter, why would the battery symbol in CM9 always show the lightning bolt assuming pin 1 VCC is not connected?
I'd appreciate any responses from other members here since I believe without USB the TP could be bricked in case some boot code gets corrupt and you are forced into WebOS recovery mode. This has never happened to me yet and I've installed a lot of nightlies but it COULD happen, no guarantees. What is inevitable is my connector will eventually wear out and my TP will only live until the bootloader DOES get corrupt, hopefully later than sooner. This could be the case with all TP's. Just imagine if in a couple of years everyone's TP's USB port goes bad. Sounds like the devs should figure out a way to fix a bricked TP wirelessly, if that's at all possible.
Thanks,

One of my Touchpad's had the same problem in Webos it said using wrong charger may not charge or something similar and with Android ie nightly the charging signal came up but it did not charge.
I spoke to HP and pointed out that I have 2 Tablets and that swapping leads or chargers made no difference all combinations worked on one but not the other.
They agreed to fix it and replaced the part. It is now working fine. And as with yours my computer failed to recognize the tablet properly.19 times out of 20 on the one time it did I was able to back up and remove Android before HP picked it up.
I would send it back under warranty or if that has expired state that it was preexisting. Otherwise as you said it is going to become pretty much unusable.
Don't let them fob you off.
Good luck

Thanx for your prompt responses. I bought my TP at the 2nd fire sale through BB in early Nov so I still got a few more months but I would rather wait a bit more since they did nothing the 1st time around. I think the connector is on some daughter board along with the vibrate device which is soldered to the main board. Doesn't sound like a big deal to repair it. Still, what makes the HP cable different then the others? Are there known cables I can get online that might be made better to always work and make better contact than the HP ones?

i keep track of the serials and they always came back the same. i have more than one pad and i asked for one to be replaced completely. we will see if that happens. but they fix only what u ask for and nothing else.
it can take longer depending on Weekends. takes 2 days to get your box, then 2 days to get it to HP, then 3- 4 days to get your fixed unit. its all done thru UPS, cant send it out on the weekends or receive it

Hi all. I know this thread is really old, but I'm finding myself dealing with similar issues. And I'm obviously out of warranty. I can't get windows, linux, or Toolbox to pick up the USB. I'm actually in a worse case scenario mention here and am stuck in meboot, TWRP, and WebOS recovery, because I had wiped the rom. It must be an issue with the USB port, I've lost track of my original Hp touchpad OEM cable, and have tried every USB cable I can find. Any help would be appreciated.
A month or two ago I started experiencing problems while connecting my S2 to the PC or laptop using the data cable.
When I connect the cable to my S2 on the PC or laptop it comes up with the balloon messages in the system tray:
USB device not recognised.
Then a short while later it comes up with another balloon message:
This device can perform faster.
Sometimes while transferring data, it will disconnect and the file transfer fails.
Sometimes if the cable is moved slightly it will cause the device to disconnect from the PC.
And, of course, the file transfers are much slower than they should be and much slower than they used to be.

I haven't touched any ROM or flashed anything on this in like over 8 months so it's nothing to do on that front.
I removed micro SD card and tried reconnecting again, still the same problem.
I've tried different computers, still the same problem.
I've used different cables, still the same problems. Tried enabling and disabling USB debugging. Same problem still remains.
The USB cables and computer and laptop work fine with my S3.
All the correct drivers are installed for the S2.
I'm resigned to thinking it's a hardware issue as I've exhausted other options. Is there a simple fix or will this need sending back to Samsung?
I've had the phone over a year now but someone told me the warranty is two years?
All help appreciated guys. Thanks in advance.

Probably because his USB port doesn't currently work properly.
@OP, this is often caused by a dirty or faulty USB port. You can try cleaning it, but you may need to replace it.
Try cleaning it out with a dry toothbrush first.
If that doesn't work, take the battery out, and try cleaning the port with a small q-tip with a small amount of isopropyl alcohol; let it dry for a while after that, then replace the battery.
If THAT doesn't work, you'll probably need to replace the part for the USB port.
If your warranty is still good, you could try to go that route, but you'll need to unroot your phone. Otherwise, I've heard it runs about $15 for the part, and you can replace it yourself. If you don't feel up to it, you can have a cell repair shop or Samsung service center do it for you, but it will probably be significantly more expensive than $15.
My opinion based on your description is the USB socket on the phone is wearing out/damaged. The USB socket is on a small circuit board separate from the main logic board. It's easy to replace and the part is cheap on EBay. Search for a disassembly/tear down video and judge whether you can do it yourself.

Thanks for the very quick responses guy. They were very thorough as well.
I will look into cleaning the port and if it still doesn't work I'll consider having it repaired. My soldering skills were excellent but I haven't done it for a few years, so may leave it in someone else's hands.
I haven't upgraded to ICS as I was very happy with my phone at the time. Also, a couple of friends who had upgraded to ICS on their S2 regretted it due to numerous problems, which put me off upgrading.
You can still use mobile odin and theres no soldering needed with the usb,it comes as a board with a ribbon cable.

I've had a look on the Samsung website here:
w ww.samsung.com/uk/support/warranty/warrantyInformation.do?page=POLICY.WARRANTY
It seems as though the warranty period on my phone is 24 months so I might just get it done via Samsung.
I'll contact them in the morning and see where I stand. If not, then the replacement USB board connected by a simple ribbon cable sounds like a doddle. I've seen a grade A condition part on ebay for about £8 delivered.
Thank you once again.

This is a Cable problem. The USB port of your device is wider now, that's why the cable doesn't fit well. Buy a micorUsb cable for blackberry, it's always very full and thick, then use it to connect your phone. The issue should be resolved.
I once had the same problem with my Nokia N8 and using a Samsung cable (which looks fuller and thicker) solved it.
Yeah warranty should be 2 years BUT youll have to unroot it first if your sending it to them.
They may also wipe your phone and stick on 4.0.4.
If you get the board yourself,check the number is going to be the same i.e the spare one I have here is GT-I9100 rev2.2.
Also other people have got a replacement board and the mic doesnt work(think the boards are sold as refurbished).
So its up to you which option you go for.

Hello, dunno if this is possible/normal but my SII got issue connecting to computer with usb. If i move it slightly, it'll disconnect/reconnect. Sometimes i have to handle the phone is some weird position or it won't connect at all. However for charging, it never has issues. How can i fix this?
There is problem with your USB cable. If you have problems while charging also, then it will be an issue of USB port of your phone.
But i tested with all cable i have, about 4..! The computer detect it but it will disconnect/reconnect as said, often.
And for ADB app such as APK Installer, it won't detect it even if comp did. This is strange, but that's how it is..!

If the cables are not the culprit, it is either the USB port on the phone or the phone itself. You may try cleaning the port, or it needs replacing. I experienced somewhat similar, what I did was do a data wipe and cache wipe on recovery, and that seems to fix the connecting/disconnecting problem.
No it's not software, i have recently reinstalled everything.. I looked at the internal usb port with a little flashlight and it looks fine, i don't get it.. I'm gentle with my devices!
Gs2 is prone to get its USB port faulty, doesn't matter how gentle you are. It can be replaced cheaply though by most of the mobile repair shops. If you want to do it yourself then check out Keith Ross' guide for USB board replacement.
May i ask.. GS2 and GS4 too..?
S2, S3 and S4 all use the same type of connector.......
The issue probably isn't as common on the S3 and S4 simply because those devices are newer and have had less chance for the port to wear out......
The connector (in my opinion) is pathetically fragile and totally unsuitable for repeated connection/disconnection...I think it's called manufacturer induced inbuilt obsolescence lol....
I have personally replaced the ports on two S2s and am having to consider the possibility of replacing the port on mine in the very near future.
Partial failure of the port is a lot more common than is realised......
My wife says I'm a phone geek....She's probably right
It's the micro USB phone connector. It's a design fault, we can thank Samsung for that. the DATA pins have "broken" from the mainboard and you have to resolder them, I did the same thing to make the data work.
Very tiny soldering.. Not everyone can do that, eh?
^this is true.......
Best to replace the entire board.....

Hi all,
Long story short, I went on a brief (1 week long) trip and just went back, and during the trip I had my HDX7 stored in a locker in powered off state. The weather during the week was rainy, but the storage locker was quite deep inside the room.
Before I go on the trip it works alright; however, when I'm back, I surprisingly found that it no longer connects to the PC, i.e. no USB debugging or MTP notification at all when I plug the tablet in.
Here's where I'm at:
No ADB and MTP recognition, either in OS or in TWRP recovery
Tablet charges normally at full speed
Different cables on hand doesn't help
Different ports on the PC, even a different PC, doesn't help
At this point I'm ready to accept that some sort of hardware damage has occurred, however, I'm still willing to know...
Is this really hardware damage, or have I missed something?
If yes, how come?
Possibility of repairing?
Thanks for your insights.

Long story short, I went on a brief (1 week long) trip and just went back, and during the trip I had my HDX7 stored in a locker in powered off state. The weather during the week was rainy, but the storage locker was quite deep inside the room.
Before I go on the trip it works alright; however, when I'm back, I surprisingly found that it no longer connects to the PC, i.e. no USB debugging or MTP notification at all when I plug the tablet in.
Here's where I'm at:
No ADB and MTP recognition, either in OS or in TWRP recovery
Tablet charges normally at full speed
Different cables on hand doesn't help
Different ports on the PC, even a different PC, doesn't help
At this point I'm ready to accept that some sort of hardware damage has occurred, however, I'm still willing to know...
Is this really hardware damage, or have I missed something?
If yes, how come?
Possibility of repairing?
Thanks for your insights.

Charging takes place on the two outer pins; data communication on the two inner pins. Look for a bent/missing inner pin. More likely one or more solder connections have broken where the USB recepticle attaches to the main board. Not a fun fix; just say 'no' if inexperienced with such mods.

While I have tools for disassembly and some experience, HDX7 is definitely beyond my ability to dismantle just to check what's wrong, let alone repairing it on my own.
Guess I'll just sell this thing cheaply to someone who can bear with transferring files wirelessly...
