Hello everyone, Please forgive my newbie question but I tried for hours to figure this out and it's still unsolved.
I tied to use my Samson meteor USB mic with OpenBSD. When I attach it, dmesg tells me that it found an new audio device. The /dev/audioctl1 and /dev/mixer1 both work for the device. Now when I try to play white noise on the integrated headphone port with cat /dev/urandom > /dev/audio1 I get cat: stdout: Input/output error and the following messages in dmesg: ehci0: Error opening low/full speed isoc endpoint. A low/full speed device is attached to a USB2 hub, and transaction translations are not yet supported. Reattach the device to the root hub instead. uaudio_chan_open: error creating pipe: err=INVAL endpt=0x01 My microphone is attached to the root hub of the machine, so I don't really get what's this all about. The full relevant part of dmesg output: uaudio0 at uhub2 port 2 configuration 1 interface 0 "Samson Technologies Samson Meteor Mic" rev 1.10/1.00 addr 3 uaudio0: audio rev 1.00, 7 mixer controls audio1 at uaudio0 uhidev3 at uhub2 port 2 configuration 1 interface 3 "Samson Technologies Samson Meteor Mic" rev 1.10/1.00 addr 3 uhidev3: iclass 3/0, 2 report ids uhid2 at uhidev3 reportid 1: input=15, output=15, feature=0 uhid3 at uhidev3 reportid 2: input=1, output=0, feature=0 ehci0: Error opening low/full speed isoc endpoint.
