I've been having a strange issue with my USB flash drives. I can't seem to copy much anything to them. It appears to copy and then hangs, then I get:
[ 6841.490036] usb 2-6: reset high-speed USB device number 16 using ehci-pci [ 6848.540029] usb 2-6: reset high-speed USB device number 16 using ehci-pci [ 6855.590031] usb 2-6: reset high-speed USB device number 16 using ehci-pci [ 6862.640026] usb 2-6: reset high-speed USB device number 16 using ehci-pci [ 6869.690025] usb 2-6: reset high-speed USB device number 16 using ehci-pci [ 6876.740023] usb 2-6: reset high-speed USB device number 16 using ehci-pci dmesg is full of these messages. Now, I haven't used any USB flash drives for quite some time (months.) I know this used to work fine. For example, it took 20 minutes to copy 300MB of data and it was all corrupt. I've tried different file systems, makes no difference. I also have a lot of USB flash drives and I've used at least a half a dozen different ones with the same results. In early January I updated the kernel to gentoo-sources-3.17.7 (which is my current running kernel.) I've done some googling and while I did find some issues with 3.10.x there's nothing recent. Does anyone know if there was a USB regression or something with the 3.17 branch? In the last month I've used 3.12, 3.14, and 3,16 before the switch to 3.17. I also switched to systemd for 3.17, but I don't think that has anything to do with the issue I have. I'm going to try to update my kernel later on, I see that 3.17.8-r1 is marked stable now. Dan
