how many USB resets per day is normal?

[Dan Jacobson <jidanni@jidanni.org>]

How many
   usb 3-2: reset full speed USB device using uhci_hcd and address 2's
is normal per day for you card reader users, as seen in dmesg?
I use udev and hal on sid.

Resets are just normal and don't mean files are going to get
corrupted, right? If files were going to get corrupted then cp(1) etc.
would tell me, no?

I note that one can reduce the number of resets if plugging indirectly
thru a hub, or using a different laptop with the same card reader.
