Karmic slow USB transfers to USB 2 stick

[Shawn Reist]

Binary package hint: nautilus

Fresh install of karmic beta 10 Oct 2009

USB transfers great (12-15 Mb/s) to a USB 2 stick, reads were 12-17 Mb/s

After a couple updates I noticed the transfer rates dropping (3-6 Mb/s; subsequently now the transfer rates are slowing down to 1.2 Mb/s

I have noticed slow transfers with Ubuntu for a little while. tried the karmic beta live CD, the best transfer rates I have seen in a while.

I even purchased a small powers USB 2 hub (possible voltage loss due to cable length affects transfer rates for testing with Jaunty (previously installed on 3rd HD. Legacy USB 1.1 still enabled, even with the LCD of Karmic running for 6 hours transfer rates were 12-15 Mb/s.

Hello,

The transfers of a 876 meg file are now taking 23 min.

the only things I can think of to do is back track.

I have all the updates in the /var/cache/apt/archives/ folder can I copy
that to an alternate directory then separate due to date for controlled
installs (i.e dpkg -i *.deb for the specific folders)

Install the live CD, do tests record information that you would
like/need; to see which date/package started the degradation of the file
transfer process.

would this work/help?

Any additional programs/scripts to help with this process if it seems
plausible.

The best transfer speeds I have seen for a little while were off the
Beta LCD, and in the first couple days after the install from the
10-16th before drops in speed started to occur.
