[App_rpt-users] ACID USB Error

The ACID build on one of our repeaters crashes occasionally after repeatedly
recording "Cannot submit data pipe for urb 0, error -22: internal error" 

I've been unsuccessful at locating details of this error online. Is there a
list of such errors available?

I'm running two nodes on the server. I've had issues when rebooting where
one node operates normally, and the other delivers choppy audio to the
radio. The URI green light toggles much slower than normal. I may have an
internal USB hardware issue. They are both on the same internal bus, and
both radios are in use, one a repeater using a GE MSTR II, and the second is
used as a UHF link. The computer is a ATOM Mini-ITX with a SATA SSD.

Once they are working after a reboot, they go for quite a while. This last
failure occurred after a "reboot" command. I read somewhere that a similar
error was caused by a known CentOS bug, so I'm wondering if I need to move
to DIAL to get a "fix," but would like to understand it better before just
moving. I don't like lurking issues :-) It operated flawlessly for about two
years prior to this. This is the second time in the past month, or so, that
we've dealt with this.

Any thoughts?
