USB stick being dismounted

<< < (2/2)

thane:
Got the problem again yesterday. dmesg showed an error when trying to journal (I'm using EXT4 format on USB) and suggested a bad USB cable as a possible cause. Reinforces my belief that it's a hardware problem I'll probably just have to live with. Might try using a different brand of USB stick. Thanks again for your suggestions!

PDP-8:
patrikg has a point.  I had a similar issue with a flaky usb mouse that drove me nuts.  External ssd's too on usb once in awhile.  Usually spammed the logs and dmesg seeing it power down and wake up.

One cure may be to disable usb-port power saving with this kernel parameter:


--- Code: ---usbcore.autosuspend=-1
--- End code ---

In most kernels this is set at 2, but the -1 (negative 1) shuts it off.  There is no space between the = and the -1 in the above.
