USB devices work with uhci, not with ehci
Hi folks, Has anyone seen this kind of thing before? All my low or full speed devices work fine.

RE: USB devices work with uhci, not with ehci
I have seen this as well (on an x86-32 desktop machine), and it turned out that my USB wireless adapter didn't work fully with ehci. When I have ehci-hcd loaded and the wireless adapter (rt2570 chipset) plugged in, I get scsi timeouts on my USB thumb drive (also SanDisk Cruzer Mini...) so that nothing works (flash drive or wireless). On the flip side, if I remove ehci-hcd and only use ohci-hcd both work fine (the wireless is only 11 Mbps, so speed isn't an issue, but the flash is much slower). This is on an older machine (my wife's), and so I have the wireless in the onboard uhci-hcd driven controller, and the rest on the add-on PCI board driven by ehci-hcd. This just happens to work for this machine, but isn't a real solution. Is there any way to force a USB device to run at lower speed with high speed module loaded and enabled for all other devices?

Is there any way to force a USB device to run at lower speed with high speed module loaded and enabled for all other devices? Hmmm... well, that's kind of similar, but not exactly what I'm seeing. I kind of doubt in my case it is an issue of the USB device not fully working with ehci, since I've tried it with two USB flash drives and an external USB HD enclosure, all of which work fine in high speed on my other computers, just not on my amd64. =( I assume most others here have had high speed USB devices working (in high speed mode) with ehci_hcd on amd64? -- Wesley J.
