Dear forum and whom it might concern,
I managed to compile usbip on OpenWrt with kernel 3.1, the daemon is running, reachable and exporting devices just fine. However, on the client side with Win7 x64 (yes, the driver is installed and visible in the device manager and yes, I am running the command as amin) I am getting well-known error messages, but I was unable to find a solution. This might be because:
a) there is a version mismatch - in this case how to I recompile the windows usbip.exe and would that help at all w/o being able to sign an updated driver?
b) some other problem, maybe the windows client is just plain broken with recent servers?

… I forgot to mention: I am not using the outdated, broken usbip package from the OpenWrt repository, but the kernel modules and userspace component from the official Linux tree 3.1.10 - so that shouldn't be the probem.
Thanks for any input you have, the linux->win scenario should be quite common.
I solved it myself: The version mismatch was the problem, I had to recompile the daemon to match the windows exe version. Now I'm running OpenWrt MIPS / Linux 3.2.2 to Win7 x64 with no problem and no bluescreens yet.
Thanks for the solution winoss. I have the same problem.
Having a look at usbip_windows_v0.2.0.0_signed\usbip_protocol.h there is a version define
#define USBIP_VERSION 0x000106
0x111 makes version 262
In the linux 3.1.10 kernel, in usbip/userspace/config.h it is defined as
#define USBIP_VERSION 0x00000111
So this would suggest the Win7 64 bit driver is older than the code in Linux 3.1.10.
Interestingly Linux 3.2.2 still has it defined as 273, so there must be provisions for backwards compatibility in the later versions of the kernel.
Off to give Linux 3.2.2 a shot.
I got it working in the meantime, and lately there's even an OpenWrt patch in patchwork that might be added sooner or probably later to trunk: http://patchwork.openwrt.org/patch/2076/
The problem is that newer kernels have an updated userspace part that doesn't work with the legacy out-of-tree versions. Once you use the kernel module with the matching userspace program (all to be found in the staging tree), it works with the windows driver from sourceforge just fine - the attached devices on the router are seen and can be used with windows. So either use the patch or cross-compile the staging userspace part yourself.
