I am in the process of writing a User Request Block (URB)driven USB2.0 device driver for a BULK TRANSFER DEVICE.
Already implemented as a NON-URB BULK DEVICE.
I know that this is KERNEL device driver
Several issues that arise:
1) Corbet & Rubini example posted
http://www.ceng.metu.edu.tr/courses/...sb/usbsample.c
has caveat
/* No USB with 2.0, make an explicit error and avoid strange ones */
#if LINUX_VERSION_CODE < 0x020200
# error "This module needs kmod, so it won't run with 2.0"
#else
2) All USB URB examples that I see posted appear to be
USB1.0
3) The KERNEL code that I am writing
I get the /usr/src/kernel/..../ errors

Will the URB system work with USB2.0 in LINUX, if so
are there any examples that show URB USB2.0 ??
