Revision 2542335ccf34cfb442d3fd842d7e78ca5e649951 authored by Jon K Hellan on 24 June 2008, 09:43:13 UTC, committed by Greg Kroah-Hartman on 04 July 2008, 01:20:37 UTC
Here's a new device ID for the ftdio_sio driver. The diff is with linus's tree as of this morning. The device is the RigExpert Tiny USB Soundcard Transceiver Interface for ham radio. (I didn't actually test this. A fellow ham couldn't get the device to work, and I suggested binding the device ID using sysfs - see "http://jk.ufisa.uninett.no/usb/". However, he had had moved on to other things by then. I guess adding the device ID to the kernel "on spec" won't hurt. The relevant part of cat /proc/bus/usb/devices shows: T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0403 ProdID=ed22 Rev= 5.00 S: Manufacturer=FTDI S: Product=MixW RigExpert Tiny S: SerialNumber=00000000 C:* #Ifs= 2 Cfg#= 1 Atr=80 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.)
