[gentoo-user] Issues with USB memory sticks

[gentoo-user] Issues with USB memory sticks

[Daniel Frey]

I've been having a strange issue with my USB flash drives.

I can't seem to copy much anything to them. It appears to copy and then
hangs, then I get:

[ 6841.490036] usb 2-6: reset high-speed USB device number 16 using ehci-pci
[ 6848.540029] usb 2-6: reset high-speed USB device number 16 using ehci-pci
[ 6855.590031] usb 2-6: reset high-speed USB device number 16 using ehci-pci
[ 6862.640026] usb 2-6: reset high-speed USB device number 16 using ehci-pci
[ 6869.690025] usb 2-6: reset high-speed USB device number 16 using ehci-pci
[ 6876.740023] usb 2-6: reset high-speed USB device number 16 using ehci-pci


dmesg is full of these messages.

Now, I haven't used any USB flash drives for quite some time (months.) I
know this used to work fine. For example, it took 20 minutes to copy
300MB of data and it was all corrupt.

I've tried different file systems, makes no difference. I also have a
lot of USB flash drives and I've used at least a half a dozen different
ones with the same results.

In early January I updated the kernel to gentoo-sources-3.17.7 (which is
my current running kernel.)

I've done some googling and while I did find some issues with 3.10.x
there's nothing recent.

Does anyone know if there was a USB regression or something with the
3.17 branch? In the last month I've used 3.12, 3.14, and 3,16 before the
switch to 3.17.

I also switched to systemd for 3.17, but I don't think that has anything
to do with the issue I have.

I'm going to try to update my kernel later on, I see that 3.17.8-r1 is
marked stable now.

Not an expert, but check contacts (if ports are not used for a long
time check if there is dust in them), if you use extension cable or a
hub, try without it (power issues), or try different port (does it
happen on all ports?)

Also check other messages from kernel, they can be useful 
diagnosing this issue.

Have you tried your previous kernel ? -- I assume you kept it around ...

Trace-cmd plugin for parsing USB 3.0 host controller driver traces
can be found here [1] .

trace-cmd is NOW (finally) in the portage tree:
dev-util/trace-cmd-2.5.1 

There is a 'game-changing' graphical diagnostic tool that is 
yet to become manifest as a ebuild or overlay, found in the
same sources as trace-cmd, KERNELSHARK.

So for now you must '[drudge]' via CLI, but hopefully one of our 
devs or power_users will whip up an overlay for KernelShark.

This is the most 'bad ass' tool going for kernel problem.
Welcome to the ftrace-->trace-cmd-->KernelShark club.

hth,
James

Tried several ports, different usb sticks, result is the same. Only
message in logs is what I posted in my original message.

Going to try a new kernel & maybe reconfigure my old kernel to systemd.
However, I'll have to do it this weekend. Too busy with other things
right now...

I'll post back if I find anything.

An update: New kernel didn't do anything. However, while checking the
filesystems, I noticed that some are FAT and some are NTFS. I checked
the partition types and they were set right.

So, for some reason, on my machine FAT- or NTFS-formatted devices simply
do not work.

I took a few of the flash drives and formatted them as ext4, no issues
(and no resets in the kernel log.) Repartitioned and reformatted as NTFS
or FAT, they don't work.

Now how weird is that?

Most of the time I use my esata enclosure when I need to move stuff off
of my computer, when I discovered this it was one of those rare times
where I used a flash drive.

I'm not sure what I can do about the FAT support, but I can try ntfs-3g
for ntfs - although I don't feel like testing that now. I'm just happy
it's not my motherboard.
