Ah yes, USB. Could be the powersave/suspend issue. Iirc, the kernel implemented it as if there was a upper limit on how long the device could take to get ready after a resume. But apparently the time mentioned in the spec was just a suggestion, not a hard limit. And many devices would take a minute or longer to come back once resumed. Lets just say that USB is a "fun" protocol, and the latest addition has not helped much.
- hga 10y agoIt was as I recall a timing/time out issue, and very possibly the one you describe, it would just have to not effect the normal keyboard and mouse USB 1.x devices, and I'm pretty sure these USB 1.x sound devices had much better than "a minute or longer" times in resuming. And, yeah, I can imagine how much of a zoo USB in the real world is....
