[PATCH] plusb added support for PL-27A1 , kernel 4.2.0-25

Show all headers | View raw

Hello all,

I made a patch to add support for Prolific PL-27A1 host-to-host USB 3.0 
link cable. It's the same platform as PL-25A1 but with USB3.0 interface 
so basically I only added right vendor/device id to get detected. 
Maximum throughput I managed to get was about 1.5Gbps using iperf. I'll 
investigate usbnet to  get even higher throughput, if you have any tips 
where to look, let me know.

Developed and tested under 4.2.0-25.

Best regards
Daniel Kucera.
