Hello! I had 9.3 on a Samsung P35 II 1600 and USB worked flawlessly. Now that I installed 10, I have some issues. Usually I have a USB-mouse attached, which works quite well, I then un-plug it and plug-in a USB-mass-storage device, e.g. a camera, or a usb-stick. Both worked with 9.3 without problems. Using 10, hotplugging does not work most of the times. I do not even get any messages in CTRL+ALT+F10. Does somebody have a hint for me, how to track down the problem. All of these devices work perfectly, if they are already plugged-in at boot. Another problem with USB is that after I plugged-in my Logitech USB-headset, suspend-to-disk does not work anymore. I hangs at unloading uhci_hcd. I can switch to a konsole and reboot though. I had a look at the suspend2disk-log, yet it did not report any problems. CTRL+ALT+F10 gives me some lines, I think the problem is: Oct 16 22:29:13 pc192s kernel: drivers/usb/input/hid-core.c: can't resubmit intr, 0000:00:1d.0-2/input0, status -19 Does anyone else have these kind of issues?
