Restart mini pci slot
Sometimes minipci slot stopping work. I don’t know the reason but we can rescan it and going to work again. Only one command you need. The command is that:
sudo echo "1" > /sys/bus/pci/rescan
After this time your pci card going to work. I tested this in Ubuntu 16.04 x64. Have a nice days.
If this doesn’t work please check: https://askubuntu.com/questions/812372/usb-3-0-express-card/865802#865802
Add pciehp.pciehp_force=1 to the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub, as detailed in the Ubuntu 9.10 and onwards section of this ExpressCard article. That solved this problem for me.
Specifically:
- Edit
/etc/default/grub. - Find the
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"line. - Change that line to say:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pciehp.pciehp_force=1" - After saving those changes, run:
sudo update-grub - Reboot.
On my USB 3.0 32G drive, it then showed up automatically.
