I am a complete noob when it comes to Android, having first got my G-Tab yesterday. I'll give some background before I get to my question.
Yesterday, I sideloaded a couple of apps by essentially copyng them over to the root directory on the G Tab. But, like most others, I found the stock OS very slow and unresponsive. So I installed CyanogenMod 7 as per some simplified directions that I found. Everything went fine. That's not the problem.
My problem is that I cannot sideload anymore. When I plug in my G-Tab through the USB, I hear the Windows two thumps, and nothing happens. I look to see if my tablet is showing up in the Winders Explorer, and it just shows a bunch of memory sticks that when I click on them, I can't access. Also, nothing is showing up on the tablet either (no dialog boxes like under the stock OS, nothing). This is a big problem for me since I don't have access to WIFI at the moment.
Does anyone know how I can make my computer and tablet see each other? If you tell me to do something, please tell me where to find it. For example, on another thread, someone advised someone else to turn on USB debugging for something, but I can't find any option for USB debugging in Cyanogenmod 7 under settings. Thanks in advance for any help you can provide.
Additional info:
Computer: Laptop running Windows Vista
Did you try swiping on the notification area and enabling USB transfer on the tablet?
If you don't do this, your computer will see the USB device but not as mass storage.

Here is where this is....
Menu >>Settings >> Applications >> Development. 1st choice, USB Debugging.
Thanks. I did swipe in the notification area, and the only notification there was that USB debugging was activated. But still the G Tablet and computer cannot see each other.
Double check in your device manager (PC) to make sure there are no issues with the drivers.
Thanks. I found it and also found out that it is turned on by default. So I guess that doesn't help.

Does Cyanogenmod 7 require special drivers? The drivers worked fine on the stock build, and nothing changed since then. Everything looks ok.
I plugged my Gtablet (CM7.02 with Pershoots 4/30/11 kernel) in to my computer just now to test. I haven't used it on this computer since installing CM7. I did just work on my boss's Gtablet the other day running both stock TapnTap and VEGAn 5.1.1 and it worked fine on his.
I plugged in the tablet, Windows 7 (32bit) said it was installing drivers, driver install completed successfully.
On my tablet I then swiped up the notification bar and tapped on the selection that said "tap here to mount USB to share files with your computer" (or something like that). The Android mascot screen popped up and I tapped "Turn on USB".
New drive opened up on my computer that was the gtablets /sdcard.
So it works and used the same driver as before.
No special drivers for CM7.
One nice thing about CM7 (or maybe Ginger) is that now when plugging in you get access to both the internal and external SD cards from PC.

My computer Vista (32 bit) at no point said it was installing drivers after I upgraded to Cyanogenmod 7.
When I swipe the notification area (and I assume that the notification area is the area at the top of the tablet's screen), I get a menu that tells me that USB debugging is activated and that's all. No option to mount USB. And no screens popped up to ask to turn on USB. None of this.
And when I plug in the USB, as I mentioned, I get the two tones from Windows, and 3 new removable disk drives appear. But when I click on each, I get am asked to insert a new disk.
That's all the info I have at the moment.
At this point, I'm so sick of it. I think that probably somewhere a switch is not flipped or a box is not checked, but I have no idea where that could be. I'm seriously considering using ClockWork mod to restore the system. But I'm loathed to do this since I spent 2 hrs. downloading Cyanogen Mod last night (I have a slow internet connection).
I would suggest that you turn off "USB debugging". That setting exists to activate adbd on the tablet, and normal users, usually, never need it. Enable "USB debugging" only if you need to use adb.
After disabling USB debugging, reboot the tablet, and then connect the USB cable to the mini-USB slot on the gTablet. As soon as you do that, on CM7, a USB Mass Storage screen with a green Android will pop-up with a message saying "USB connected" and button to "Turn on USB Storage".
Click the button and a warning that "If you turn on USB storage, some application you are using will stop and may be unavailable until you turn off USB storage.", will appear. Select OK. The green Android will now turn orange and the screen will say "USB storage in use".
Use the "Turn off USB storage" when you're ready to wrap up.
Ok. I think I might have solved the problem, but some intervening events makes me not sure. Basically, I restored to factory and then put in a different ROM, VEGan7. However, while doing this, I think I might have found the solution to my original problem.
It turns out that it does seem to be a problem with Windows, or at least with Vista. I had the same problem with VEGan7. But this time, I right-clicked on the "removeable disk" that appeared under "Computer" (where you see all your drives) when I hooked up the G TAB via USB. After I right-clicked, I selected properties and then clicked on the "Hardware" tab. You will see a list of all possible storage devices to associate with that icon. I chose the one containing the string "Tegra2" and I was off to the races. I was then able to perform the actions mentioned above about activating the USB on the G Tab.
I suspect I could have used this technique with Cyanogen 7. The only thing that I question is that I saw 3 removeable disk drives appear and not just one. I hope this helps someone else who might run into the same problem.

Did you by any chance have an external micro SD card on the tablet?
If so, I'm thinking that you saw the 2 SD cards + the APX debug mode device.
flash this zip (in post #3) to mount the internal storage as an SDcard instead of EMMC. If you run that then you should be able to mount the storage when running CM7
http://forum.cyanogenmod.com/topic/20913-cyanogen-7-viewsonic-g-tab-usb-connection/
also your other option is to boot into Clockwork recovery then go to mounts/storage and mount usb
you should then be able to transfer files back and forth

No, just got the tablet. Didn't have time to fool with external Micro SDs.

Thanks, I'll give it a try. What are the ramifications of mounting the internal storage as an SD card instead of EMMC? Do I lose performance? I mean, there must be a reason that the default is EMMC.
I wouldn't want to boot into Clockwork every time I want to transfer something, apps or even music and videos. That would be a real pain. Actually, I was surprised at how long this tablet takes to boot up after a complete shut down.

From what I have read that's the way that Gingerbread does it. Some programs actually have problems with that configuration, that's why people do this.

Do you think you might post the file here. When I go to that link I'm not allowed to download it. The irony is that that link says it came from here but I've used the search and I can't find it here. Maybe it is just day after Cinco de Mayo problems I'm having?
USB port not working, so I cannot connect to the computer to do nvflash or adb.
Getting android.process.acore has stopped message after start. I have the stock update.zip in the internal sd card because of which every time i do a recovery it trys to install the stock update and throws teh FC error. Not able to get past the FC error. Tried putting the clock work recovery in the external sd card but because of existing update.zip in the internal sdcard, external is not read.
I am not able to get past this. Any help is appreciated.

What makes you think your USB ports are not work...maybe you haven't downloaded the correct stuff and configured it correctly (adb & apx drivers).
Go here http://viewsonic-gtablet-for-dummies.webs.com/ and follow code red. Follow the instructions step by step & download everything from the links on the site. If you still have a problem, post a message on that sites forum.

Don't take this wrong...just asking questions to try & help out. You would only see an unknown device if you had not installed the drivers (apx and/or adb). Once you have installed the adb & apx drivers for one gtab it will not be unknown. Are you sure you are entering apex mode correctly...hold power+volume - ? Screen will display 3 birds then go black!
Yes. I went to the apx mode correctly. Still did not see my device recognized.
I am looking for a solution for bypassing the FC temporarily or to clean the internal sdcard. once the internal sdcard is cleaned, i can use the external sdcard to do the clock works mod and go further

Take a look at this thread & see if it helps http://forum.xda-developers.com/showthread.php?t=853537&highlight=android.process.acore
I am not able to get past the android.process.acore error. I think i will be able to fix it only if the usb drive works, i am going to call viewsonic and see if they will take it in for warranty repair.
I am running CM9 4.5.1 with GApps v12 on an Atrix 4G. The issue I am having is that when I connect via USB cable to my XP system, my PC detects the two sdcards (internal and external) but I can not access either one of them..."Please insert disk into drive" like they are not formatted.
I did find that the external sdcard is now being seen in the phone as folder EMMC and both of them have data so I don't think it is a format issue.
I have tried to connect via USB using the MTP and Mass Storage Option and rebooted the phone both times after the change was made. Neither attempt worked.
I have searched through the forum as best I could but with the CM9 thread pushing 1000 pages, I'm not sure if anyone has come across this. If so, what was done or are there any suggestions out there? Thanks.
Never mind, I figured it out after installing new USB drivers from Moto and trying everything else. Found out it was a simple/stupid oversight on my part. So if this happens to anyone else....
Even though I had Mass Storage enabled in the settings, when I connected the phone via USB to my XP Pro Pc, I had to pull down the notification bar, select USB storage, and turn it ON. I guess by default it is turned off. Once that was done, I am now able to access the sdcards on my PC.
I did find during all of the research and trial/error that the sdcard-ext is now the sdcard and the sdcard is now emmc in the folders. I believe there is a way to change this (xda thread) but I can live with the way it is.
I made a few backups using CLockwormod onto my int and ext SD cards. I now want to transfer them to my computer to save some space, but that's where the problem lies. I'm not sure why but it automatically disconnects me and gives me an error as soon as I attempt to move any of the backup folders from the SD cards to the PC. Moving image files to and from the phone and PC is fine. It's as if some program locked those folders and I can't figure out why. I have Rom Manager and Clockword Mod Recovery installed. Please help, my only other option is to delete the backups through rom manager. USB Debugging mode is on
THanks
Found a guide outlining the steps. My problem is with Step 4.

Droid explorer
Download this program to your computer to transfer the files
http://de.codeplex.com/releases/view/87215
I managed to connect my device using droid explorer, located the backup folder in the internal sd, and clicked on "copy to local computer" and it is still hanging at the transferring files screen with 0 bytes moved and "Copying 0 items". I'm wondering these backup files are being used during the transfer, which could be preventing me from moving them. Doesn't make any sense since i dont think any background processes would need to use backup files...
I gave up. The same thing. Phone doesn't stay connected. So I went back to my old habit of using ftp file transfer. I use Filezilla on the PC and use FTPServer (https://play.google.com/store/search?q=ftpserver) on the S3.
I've already accounted for the usb disconnecting on screen lock. Set display to never turn off while idling, turned off power saving mode, disabled screen lock, and that maintains the usb connection...but the problem is that i can't transfer files! Guess my only other option is to upload to dropbox u.u
UPDATE: I see my phone in My Computer but kies will not recognize it. This is a stock rooted Samsung S3 SGH-T999. Turned USB Debugging off, Updated Kies to latest version, Installed samsung usb drivers
I have a nook that had 1.4.1 on it before I put the Nook Zergy root and patch on, about a year ago. The other day I installed cm-7-TEAM-B-BETA1-signed and gapps, and then cm-10-20130123-UNOFFICIAL-acclaim and gapps. Everything seems to be going well except the PC does not see the internal nook sd card (My Nook) or the external SD card. There was also a broken driver in the device manager that said Barnes and Noble Nook, so I reinstalled the Android Composite ABD Interface driver in the device manager, but nothing seems to get the PC to see the nook or sd cards that I put in. The computer drive list shows Removable Disk (E) and Removable Disk (F) and when they are clicked it prompts to insert a disk. My computer is Windows 7. Somewhere along the way I must have done something wrong. It doesn't say My Nook or show the sd card. I have tried reformatting the external SD card.
Is there a way to get the PC to recognize the nook - have it show up on the PC when connected via usb? Will I have to revert back to stock or should I try reflashing the Rom I have, or installing a new Rom? I forgot to make a backup of my 1.4.1 version before I started custom Roms. oops. :silly: :crying:
Are you getting prompt on the tablet notification bar? It should give a message like 'touch to transfer files to computer ' or something like that.
Also try disabling USB debugging mode in settings > developer options
And if you're considering flashing new ROM, go to cm10, no need to revert to stock to fix USB issue.
Edit - missed that you were already on cm10. Usb works fine for me though on cm10
Your Tablet might be set to work as MTP device. Included is a picture of what i looks like in my Windows file explorer. You may need to disconnect and reconnect, close and re-open the file explorer for it to show up.
Thank You satan and asawi - It's working now. Unchecking the developer options and going into the storage options to mount the usb fixed it. I also reformatted the card after I saw that root card would work, but not the one I had in the nook. Everything is working, yay! You saved me from a lot of frustration trying to figure it out.
