Hello,

I suspect that I have faulty hardware related to a USB 2.0 multicard reader which is built-in to my computer. My computer crashes (freezes) from time to time and it's difficult to find the cause (since I no longer can read any log-files after the freeze)

I've seen some IO errors related to a usb device

lsusb gives:
Bus 001 Device 003: ID 0bda:0158 Realtek Semiconductor Corp. USB 2.0 multicard reader

dmesg | grep usb gives:
usb 1-5: new high speed USB device using ehci_hcd and address 3

(I assume that the Device 3 indicates the USB device at address 3 here, but I am not sure)

I understand I can blacklist a device (or at least a loaded module) under:
/etc/modprobe.d/blacklist

if I run
lsmod

I cannot find out which of the 50 or so modules relates to the multicard reader and if it relates to the multicard reader alone.

Or perhas there is another way to disable the multicard reader.

Any pointers would be appreciated.
