Re: sam7utils

Hi Kevin, sam7 can talk to the device either by using libusb, or by utilizing the emulated serial port of the Linux kernel. You have compiled sam7 to use usb directly, so you have to rmmod usbserial and/or cdc_acm, because they will block your attempts to talk to the device via libusb. This is the error message you've seen in your kernel log. (check io_libusb.c (usb) and io_posix.c (emulated serial port) in the sam7utils source code, it unfortunately provides very little feedback if things don't work out well) Chris
