Hi, I just updated to this morning's RELENG_5 and thought I'd give USB 2.0 a try to speed up data exchange with my USB sticks. The controller is correctly identified, it seems:
ehci0: <VIA VT6202 USB 2.0 controller> mem 0xdbfdf700-0xdbfdf7ff irq 3 at device 16.3 on pci0 When plugging in a USB stick, it is correctly identified, too: umass0: USB Flash Disk, rev 2.00/2.00, addr 2 da2 at umass-sim0 bus 0 target 0 lun 0 da2: < USB BAR 2.00> Removable Direct Access SCSI-2 device da2: 40.000MB/s transfers da2: 124MB (255744 512 byte sectors: 64H 32S/T 124C) I can also list the content of the FAT filesystem with mtools' mdir command. When trying to copy a file from the stick to a local filesystem, however, mcopy is almost immediately stuck in state "physrd" (according to top(1)) after copying a varying number of bytes (between 100 and 2200 KB is what I've seen so far). I cannot kill the mtools process, but pulling out the USB stick helps - it panics after a few times of doing that, though. I thought it might have to do with IRQ sharing first, but according to "vmstat -i" and dmesg, ehci0 doesn't share its IRQ with anything else. I know that the ehci(4) man page says the driver is not finished and quite buggy, but that doesn't mean I shouldn't report a problem, right? ;) Any ideas? Stefan
