Hello Martin, I tried to compile testusb (http://www.linux-usb.org/usbtest/testusb.c) as well as you did (good news, I got the USB driver working): hoe...@wks02-lin:/mnt/ext3_data/projects/hasler/emdebian_eval/testusb$ arm-linux-gnu-gcc -Wall -g -lpthread -o testusb testusb.c In file included from /usr/arm-linux-gnu/include/errno.h:36, from testusb.c:27: /usr/arm-linux-gnu/include/bits/errno.h:25:26: error: linux/errno.h: No such file or directory In file included from /usr/arm-linux-gnu/include/sys/ioctl.h:27, from testusb.c:33: /usr/arm-linux-gnu/include/bits/ioctls.h:24:24: error: asm/ioctls.h: No such file or directory testusb.c:34:32: error: linux/usbdevice_fs.h: No such file or directory testusb.c:60: error: expected specifier-qualifier-list before ‘__u8’ testusb.c: In function ‘is_testdev’: . . .
