Dear Olvier, >>> Could you get dmesg of 2.6.2(7/9) with CONFIG_USB_DEBUG and debug >>> activated in drivers/usb/class/cdc-acm.c ? FYI, I compiled 2.6.29.1, and it doesn't work with this kernel either. I'll compiple with the above flag, and will provide output. should I just paste dmesg for when the cdc-acm module is loaded?
