For newer kernels ( >=2.6.28 ), try linux-staging code!This directory contains the source code of usbip drivers for mainline kernel.[How to make USB/IP drivers]	1. cd $(top)/drivers/{version}/	2. make KSOURCE=/usr/src/kernel-source-2.6.20		KSOURCE is the directory that your kernel was built.	3. If succeed, usbip_common_mod.ko, vhci-hcd.ko and usbip.ko are built.	4. Copy these kernel modules to client and server hosts.	5. Don't forget to make USB/IP tools. See $(top)/src/README.[Tips]	Read http://usbip.wiki.sourceforge.net/how-to-debug-usbip .	If you want to see a lot of debug messages,		make KSOURCE=/usr/src/kernel-source-2.6.15 DEBUG=y	It is also a good idea to recompile your kernel with CONFIG_USB_DEBUG	and CONFIG_USB_STORAGE_DEBUG flags.	To disable debug output temporaly, write 0 to usbip_debug.	If you use ZSH,	   echo 0 >| /sys/bus/platform/drivers/vhci_hcd/vhci_hcd/usbip_debug	   echo 0 >| /sys/bus/usb/drivers/usbip/*/usbip_debug
