Hi,
I have problem with my Kindle e-book reader. It worked fine last week, but now it keep disconnecting from laptop.
When I plug it in (using USB 2.0), it is recognized, according to lsusb, but after few seconds it "disappears" from list.

and dmesg shows this:

For powersaving I use tlp and I have this device blacklisted, so it shouldn't be the cause. And the autosuspend for USB is set to 2000s. I tried to google but nothing helps.
Thanks
Edit: It was because of two bad cables, the third one works. Sorry
