Hello, I wrote a driver for Genesys Logic's GL620USB-A to test my USB PC-to-PC link cable. This controller is old (USB 1.1 age!) but GL620USB-A based link cable is still sold at eBay.
To support GL620USB-A, I modified sys/dev/usb/if_upl.c (Prolific PL-2301/2302 driver) and added some stuffs. These kind of devices simply provide communication pipes on USB, and I heard that PL-2301 driver can drive GL620USB-A with adding idVendor/idProduct. [1] This is simple resolution but it limits the peer to OpenBSD box. So I wrote GL620USB-A driver as new one to be compatible with Linux's usbnet driver. [2] I named the driver ugl(if_ugl.c) and tested it on OpenBSD-current/amd64 with Slackware-14.0. The patch is at http://www2192ue.sakura.ne.jp/~uaa/gomitext/2013/20131023/20131026.diff Is anyone interested in the driver for such an old device? Any comments and advices are appreciated.
