I have plugged the drive into Windows XP and transferred a file to it from another computer over my 100Mb LAN and it sits at around 9,000KB's so it is definitely capable of going faster than it currently is on FreeBSD. > > Cheers. > > -Chris > > -------------------------- > root@spunky2 <mailto:root@spunky2> :~# usbdevs -v > Controller /dev/usb0: > addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 1.00 > port 1 powered > port 2 powered > Controller /dev/usb1: > addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 1.00 > port 1 powered > port 2 addr 2: full speed, self powered, config 1, USB TO IDE(0x0702), vendor 0x05e3(0x05e3), rev 0.33 > Controller /dev/usb2: > addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), VIA(0x0000), rev 1.00 > port 1 powered > port 2 powered > port 3 powered > port 4 powered > Controller /dev/usb3: > addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 > port 1 powered > port 2 addr 2: full speed, power 160 mA, config 1, EZ USB/Ethernet Converter(0x0200), SMC, Inc(0x0707), rev 1.01 So you have an high-speed controller (ehci), but you device is attaching to the full-speed controller (uhci). Your transferrate is not surprising with this setup. Does it make a difference if you connect the device after booting? You may also want to try another high-speed device or NEC based controller - VIA ones are known to have problems. There have been some workarounds for VIA based controller - they might help you or not. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
