[PATCH] net: plusb.c

[Heiko Bauke <heiko.bauke@snafu.de>]

[-- Attachment #1: Type: text/plain, Size: 402 bytes --]

Dear Kernel-Developers,

note that the plusb.c driver for Prolific PL-2301/2302 USB Host to Host
Link Driver may be used also for Prolific PL-2501 devices if a rather
trivial patch is applied to plusb.c.


	Regards,

	Heiko
