[Kobo] Can't connect via USB. File system busy...

[xversion1]

I can't connect my Kobo to my competer via USB port. KOreader always says "file system busy...will restart" kind of. It didn't happen before but I'm not sure it started to behave like this from when.

I'm going to need the full details of what's actually shown on screen.

(Or the system logs).

Hi. Dropbear (the SSH server) is running from the partition you're trying to export via usb. You should disable the SSH server before starting an USBMS session.

Or, better yet, switch to NiLuJe tools, which include the same ssh server (and other goodies), running by default at boot and outside the mountpoint you're trying to export.

Yup

Could you elaborate? Am I suppose to use the root file? It seems too much for my need. USB sharing worked before. I just need it to work again now.

Edit: I figured it out. It's because I left SSH on all the time. I thought I just need to turn off Wi-fi to disable SSH, but obviously it's not the case. SSH still affects somehow even if there's no internet.

It has nothing to do with internet. It is how the filesystems work: you can't unmount one if there's a file opened inside. No matter if the file is a picture you're viewing, a document you're editing or a binary you're running.

The only workaround for OSes to "force unmount" a filesystem with opened files inside is to get a list of file descriptors for the given mountpoint and kill the processes that hold those descriptors.

Didn't know how I hadn't seen your first reply above NiLuJe's before. Costs me a lot of time to run through pages from NiLuJe's link trying to find the solution. Now looking back I see you have already pointed out the problem. How silly I am.
By the way, I have already run koboroot from other sources on my Kobo several times to fix other something, like language display. Do all those things I fixed gone if I use NiLuJe's tool? I'm afraid it will overwrite them.
