Hi

I'm trying to get the FreeRTOS demo with USB CDC for AT91SAM7X256 to work under Linux, using a SAM7-EX256 board.
The driver seems to work fine with Windows XP, using the (from FreeRTOS) supplied .inf-file. A com-port shows up in the Device manager, and seems to be able to get some chars from it.
Plugging it in when running Linux (kernel 2.6.24) I get these messages:

but nothing shows up in /dev-fs. I'm not very familiar with how USB works, and I don't know if the problem is at the host side, or the client. I would be very glad if someone could point me the right direction of what I'm doing wrong.

Thanks in advance!

Greetings,

You have probably solved this issue by I too searched a lot to find the solution.

I found that the usbserial module with vendor/product numbers as parameters was not the way to go. I found this cdc-acm patch, which worked perfectly for me...
