Hi.
I was trying to bring together Linux & Windows usbip and faced a problem
with currently published on SourceForge windows driver and tools.
usbip.exe -l <host> is saying:
usbip err: ... (usbip_recv_op_common) recv op_common, -1
...
Debugging and tcpdumping showed that problem lies in that Windows side
thinks it speaks 0x0106 version of the protocol and Linux side think it
is 0x0111. Git tree of Linux shows that its define in
drivers/staging/usbip/userspace/configure.ac USBIP_VERSION was changing
0x0106 -> 0x0100 -> 0x0111 without obvious (to me at least) reasons.
So Linux-side rejects connections because of protocol mistmatch.
Currently, I have recompiled usbip-utils on Linux system with fixed
version and it became speaking to Windows now. But I have not tested
devices yet.
I think this should be fixed somehow in usbip-utils - by downgrading
version, or accepting other compatible versions.
