world’s slowest USB

I tried copying about 180MB of files from my old Thinkpad onto a USB key using the mini-ITX box last night. It’s supposed to have USB 2.0 High Speed, but it certainly hasn’t; it took several hours. It managed a little over 5 Kbytes/s on a single file.

By comparison, the iBook moved the same amount of data from the key to the desktop in under four minutes. That’s more like it.

I wonder what could make the mini-ITX box so slow? As far as I can tell, there are no USB1.1 devices on the bus. Unless the device was mounted ‘sync’ (where every write isn’t buffered, but immediately written to the USB key), it’s a mystery.
