Hi there!
I'm running on some issues related to USB reliability.
Scenario: A 4-port serial to USB interface and a USB printer attached to
uhci.
Workload: Printer uses to be idle. Serial port is being polled quite
frequently, but has almost no traffic -a few chars go in/out the ports
every 10ms or so-.
Problem: Every now and then, maybe 2h, maybe 48h, USB stops working. All
comms falls at once, and printer doesn't work.
Suspicion: When lpr runs the printer, chances to hit a USB lock seem to
be scaled by a x100 factor.
Ridiculous hypothesis: May I have been experiencing some misinterrupt
issues?
I'll try to get a nice, charming and repeatable error to get up to this.
Regards!
Dani
