I bought a Zyxel NBG5715 also to share my USB peripherals. I've installed the netusb share center, but it causes bsod on my 2 windows XP SP2 pc (error 0x0000007E ( 0xC0000005, 0x00000000 ...), while it works fine with windows 7. I don't want to upgrade SP2 to SP3 since the pc are old and SP3 slows them down. Do you know if to enable USB over ethernet a specific windows update is needed? I've tried to update the network cards drivers, but it didn't help. Any idea is welcome. Thanks.
