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: Code: usb 3-2: new full speed USB device using uhci_hcd and address 21 usb 3-2: configuration #1 chosen from 1 choice 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! /Olle

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... /RaceMouse
