First of all, brand new MX LINUX user here. Been using this on a 10yo gaming laptop for 3 months now. This is the smoothest and most stable distro I have had uptil now, after having used several other ones like Mint, Ubuntu and "regular" Debian.
I am however experiencing a rather annoying problem with my USB ports.
Whenever I connect my card reader,
(i.e. ID chip / "smart" or bank chip card reader like this:

or my smartphone or tablets,
they power up or charge for 2-3 seconds and then lose connection again.
In the case of my smartphones or tablets, I then have to change my phone's configuration to "File transfer mode" and then go to MX Linux File Manager and hit the Android phone or tablet, in order to restore connection. This is annoying but at least I can get it to work and charge.
In the case of my card reader, however, this one obviously is not visible in the File Manager, so it just remains dead.
I have tried several things already, so FYI:
- switching hard disks and getting back to the horribly slow Windows 7 solves the problem immediately. So I guess it has nothing to do with the cable or the reader.
- connecting to my other laptop with Debian Linux solves the problem too. Which makes me think it really is a distro-specific issue.
- even with the card reader seemingly dead, it is in reality still visible (but not usable) when I use the usb-devices command. The reader is in the list.
- resetting the usbmuxd just makes the whole thing start over again: it powers up for 3 seconds and then goes out.
- the same issue occurs on all 3 USB ports (2 left + 1 right port configuration).
- sliding a smart card in the reader does not make any difference; it stays dead.
- I have a wireless mouse with a USB dongle connected to one of the ports. This one works perfectly.
No idea as to what to do next... Since my distro has worked perfectly until now, I'd rather hear your opinions first, before starting to mess with configuration files and risking to lose my current stability. Thx in advance!
