I know this subject is all over the internet (so to speak), and I've read dozens of threads on UF, Launchpad bug reports, etc., but none seem to address the problem. In my case, one one PC I'm dual booting Windows 7 and Ubuntu 11.04; an 8GB USB flash drive seems to work fine in both Windows and Ubuntu, but my digital camera is appallingly slow on Ubuntu. In Windows, transfer speeds are around 12 - 15 MBps; in Ubuntu it's in the KBps range. I haven't done extensive testing with the flash drive, though it seems to work ok, but the camera is obviously slow.
On another PC, everything is slow; the same flash drive transfers in KBps. An external HDD is the same.
If there are no solutions, does anyone know if this bug will be addressed in 12.xx?
