I installed Linux Mint recently, everything seems fine, except my USB 3 drives won't mount when plugged into USB 3, they don't even light up. They will only mount when plugged into a USB 2 port. My USB 2 devices however, work fine in both USB 3 and USB 2. AFAIK, USB 3.0 drivers have been in the kernal for years, so why isn't it working? I believe I had a similar issue in Fedora 30, but I don't currently have it installed, so I can't test it.
Here's what I know:
* | Port | Device | USB 3 USB 2 ---------------- USB 3 | | x USB 2 | x | x x: denotes working
lsusb suggests that there are USB 3 drivers installed
lsusb Bus 001 Device 002: ID 8087:8000 Intel Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 003: ID 1532:021e Razer USA, Ltd Bus 002 Device 002: ID 2516:0034 Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I followed these instructions USB 3.0 ports not working, but I'm not sure how to determine which driver I need to check the Kernal configuration for, nor where in the very long output from
/boot/config-126.96.36.199-generic I need to look, or for what to look.
This is what
lspci is saying
lspci | grep -i usb 00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04) 00:1d.0 USB controller: Intel Corporation 8 Series USB EHCI #1 (rev 04)
I've also tried editting the grub cmdline to include
iommu=soft as suggested in USB 3.0 not working in linux mint , but that didn't work. Possibly the instructions are only for the old GRUB?
Daniel Quinn had the same problem over at USB3 Hard Drive Not Recognised by Linux but his solution is a bit inconclusive, only that his USB 3 is currently working for him. Perhaps it has something to do with the Kernal and toggling options, then rebuilding it changed something?
Any or ideas or suggestions on how I can get this to work?
