Weird USB problem w/Midiman UnoForum: Other Help Topics Topic: Weird USB problem w/Midiman Uno started by: tayloratosu Posted by tayloratosu on April 07 2007,22:43
I'm using DSL 3.3 with a Norhtec HyperClient (www.norhtec.com) using a USB stick as my HD. Nice little computer, looks a bit like a Damn Small Machine. This box has two USB ports. I'm trying to get DSL to recognize my Midiman Uno, a fairly well-known USB MIDI interface. Here's the deal:- If I plug the Uno into port #1 and my USB stick into port #2, everything works fine. Lsusb shows the Uno is recognized as a Midiman device, and MIDI-out works. Sort of. Sometimes there are problems. - If I plug the Uno into port #2 and the stick into port #1, then lsusb shows the Midiman device is connected, but the MIDI connection doesn't work at all. - If I plug a powered USB hub into port #1 and plug the Uno into the hub, then lsusb tells me that it thinks the Uno is really a memory stick made by Feiya Technology Corp. (whaaa?). Other USB devices are recognized just fine. I realize that the short, simple solution is to plug the Uno into port #1. Ideally, though, I'd like to leave the Uno plugged into the powered hub all the time and use port #1 for other purposes. Now, ordinarily I'd chalk this up to some sort of hardware/power supply glitch or something, but I don't have this problem when I boot this same machine from, say, a Knoppix Live CD. So, I was wondering if anyone had a clue as to why this might be happening with DSL. Is it a problem with the kernel, the way the driver is compiled, or what? Thanks, Doug |
