I got this problem using ubuntu 12.04, fedora 17 and linux mint 13 and 14 on my hp ENVY 4 1050ca
cannot read SD cards when plugged to an external reader, or when plugged directly to the built in card reader.
dmesg shows the following message
- Code: Select all
unable to enumerate device on port x
gparted and disk utility do not recognize SD devices as well.
Curiosly, when my card is plugged to the external reader and I plug a second USB device, it automounts and it is read with no problem; also if it is plugged to the external reader at the moment of powering the computer it automounts... but the if it is unplugged it doesn't work anymore.
My windows partition is able to recognize de SD device with no problems though (both using the built-in and the external reader.
Hope anybody has an idea of what to do, i have been trying to solve this for a bunch of months now!!
