cannot make drivers for debian @ 2.6.30

[argd]

hello,
i've installed usbip package, but i got error when i try to run usbipd:

    usbip err: stub_driver.c:  33 (open_sysfs_stub_driver) usbip_common_mod.ko and usbip.ko must be loaded
   
    ** ERROR **: driver open failed

so,  i tried to complie staging driver, but errors were there: 

      #make M=drivers/staging/usbip

and, for sure, modprobe works without any success:

    # modprobe usbip
    WARNING: Error inserting usbcore (/lib/modules/2.6.30-1-686/kernel/drivers/usb/core/usbcore.ko): Unknown symbol in module, or unknown parameter (see dmesg)

    FATAL: Error inserting vhci_hcd (/lib/modules/2.6.30-1-686/kernel/drivers/staging/usbip/vhci-hcd.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and, finally, dmesg says:

    usbip_common_mod: module is from the staging directory, the quality is unknown, you have been warned.
    usbip_common_mod: disagrees about version of symbol kernel_recvmsg
    usbip_common_mod: Unknown symbol kernel_recvmsg

please, correct me, where i was wrong?
thanks!

oops… epic fail there… probably, i've forgotten to patch sources before compiling… sorry for that noise…
rolled back to 2.6.26 and have successfully compiled driver.
thanks!
