The following is formatted in line with the info here: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Kernel.org_Format and sent as advised at the end of this bug report here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1032342 Thanks in advance for your time, I very much hope I've minimised any wastage of that precious resource. regards, -mat Summary: 090c:1000 file transfer to/from USB 2.0 flash drive, via 3.0 port at best 50-60 Mb/s Description: USB transfers to/from flash drives are very slow. Disk Utility reports the various drives I've tried are connected at 480Mb/s, but it's rare to see transfers faster than 50-60Mb/s at best, probably less as nautilus only reports average speed which is skewed by the first 300Mb being buffered. Sometimes I get the first 300MB very fast followed by very slow and ending with a long pause while the write buffer writes out, sometimes they're just very slow from the start. Doesn't seem to matter if I'm transferring one big file or lots of little files. Seems faster with USB HDs. Flash drives I've tried so far are all working fine in other OSes on the same machine. Also occurring with bleeding edge kernel (which I'm using because anything younger won't suspend properly on my machine), 3.5.0-999-generic #201207280406 SMP Sat Jul 28 08:07:29 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux. The reason I'm reporting it here rather than at kernel.org is that I don't think it's a kernel bug, I think it's to do with Debian/Ubuntu's kernel patches. Because it doesn't happen in the live version of Fedora 17 I tried, but it does happen with Debian Wheezy. Windows 7 is also fast. Laptop is a Toshiba L830-114. Reproducible by just using the USB ports to transfer files to/from a flash drive. Transfers to/from a USB HD seem quicker but are hardly what I'd call fast.
