Hey everyone, I recently obtained a female usb a to male usb mini b adapter, which will allow me to plug any usb device into my eris, but I cannot for the life of me figure out how to put the phone into usb host mode, there are tons of articles about putting the og droid into host mode with a micro usb adapter shorted out but will that work on the eris? and do I need a custom kernel to enable host mode?
This may not be possible with our device. So far no rom or "hack" for our Eris has offered a USB hosting option.

Has anyone figured out if its possible to use the ExtUSB (sync) port as a USB host port? I'm guessing the communication lines could be controlled with software, but that you would have to use an externally powered USB hub (or devices that are externally powered) unless the +/- charge lines are 2-way.

I don'ty know the answer, but... what for? The X7500 has the cable to allow USB devices connect to the USB host... so? And for sure you will need a cable to convert mini USB to female regular USB... so is not a matter of money or carring a cable I guess.
Mostly techie curiosity. I figured since someone already figured out how to reroute internet sharing to make a wifi host, someone else must have looked at that normal-looking usb port and thought about making it work like a usb host. I'm a programmer but I don't have time to work on that...

unfortunatly the chip that does that feature is not capable of that.
if you look at the schematics of a root hub it has 1 main chip that is the hub controller, and slave chips for each of the ports. a device interface has a diffrent type of chip that's intended to be connected to a root hub connection port. thusly no software fix could be made too convert a port intended to be a connection point into a root hub port
mind you the 4-in 1 cabloe is cheap enough and i saw at least 1 site via google that had a usb port only cable for the sepcial connector
so is worth looking at that.
Hey - do you have the details of the company selling this 'usb only' cable?
Thanks for the input. Just curious if it could be done, I hadn't tried to look up the schematics. I second the request for the info on the usb-only cable, that would be perfect since they already gave us a vga cable...
Would this "USB cable" allow me to use a 149GB externally HDD caddy like I managed on my Dell x51v Axim's CF to USB slot, as the 4 in 1 cable isn't cutting it?
Thankz
There are lots of posts related to external HD and X7500... in general most of them (99'99%) don't work properly. In the webpages from HTC said that the 4-in-1 cable only admit mouse, keyboard and pen-drives.
I bought a micro usb to usb female adapter so I can use my usb wireless adapter so I can put it in monitor mode (for legal purposes only)
How would I get this to work
I plugged it in and it just sat there doing nothing
I also tried with usb flash drives and nothing happened
Any help?
Hi,
Having just tried female to female usb connected to the oem usb cable by samsung, was hoping it will be able to connect and detect a flash or external drive but it did not.
So the question is this, since a usb is universal, would it be because of the oem cable or missing support from the kernel?
Even if power is supplied through, nothing was detected but power and it started to charge.

Good to see that, as it should be handled by the o/s...
USB Host mode?
Seen a youtube video introduced a special usb dongle as an accessory which turns the microusb port into usb host mode and it will allow keyboard and various other devices to be connected.
Seems like it is not a usb host port on its own.
You need a USB cable that supports OTG. You can get one for a few bucks from Amazon. The kernel already supports attaching all kinds of USB devices, so just make sure you have the right cable.
Hello,
Does someone know how archos managed to block certain devices from the 3G usb port? I am studying the kernel source codes and the filesystems of several roms and a cannot find any references to some blocked devices. (Yes I am a expeienced C(++)/linux developer) Most devices do work on the OTG port.
Memory sticks seem to work but when i plugin a mouse of keyboard the folowing line appears in dmesg:
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
What is different on the 3G Usb port?

Good question. I'm not a developer but I have had that happen on a few (older) USB drives as well. Surely it couldn't be and old usb1.0 standard or anything that isnt enabled?
I just figured that it was a power issue thumb drives use almost no power, I'm thinking that archos designed the 3g stick/port to provide power on the low end of USB spec 5v DC and 0.5-0.9 amps.
I'm just going to link to my other post HERE about a powered USB hub. has anyone use a external battery to charge tab and do you get fast or slow charge?
I have connected an OTG cable to my device, I also have a powered USB hub connected to the other end of the OTG cable, When I try using a male to male USB cable to go from the USB hub to my computer my phone does not talk to the computer. Can I by making a special cable, have my phone talking to the computer and OTG?
I hope I explained this well enough
Thanks hope this helps you help Clancey Aggen

USB works via a type of slave/host setup. A typical scenario would involve plugging your device into a PC for file-transfer, in which case the PC is acting as 'HOST', and the device is acting as 'SLAVE'.
However, If your phone is operating in USB OTG mode then it is operating in host mode and therefore your PC would be unable to connect, as you have two devices hosting connections, but neither is seeking connection. Overcoming this limitation although plausible, is practically speaking, a waste of time in presence of other solutions.
The cable ends determine which mode to put it's respective device in. The Male MicroUSB-B end (the OTG end) has an extra pin that's jumped to another. This signals the "OTG" host mode in the device. "OTG" only applies to the MicroUSB, as the "On-the-go" functionality means it can be either host or slave.
May I ask what you are attempting to accomplish and/or why you need this setup? Just trying to transfer files or more?
Edit: my theory is you expected something akin to two-devices on a network hub. A typical USB hub is slave-device, used to share a bus lane together with other usb slave-devs, e.g. "turn one port into 4". Do not confuse with the similarly-named Network Hub. While it technically is still serial communication, thats on a whole 'nuther level functionality-wise. (Nethubs echo any received messages across all lines. USB does not do this to my knowledge.
