First of all, sorry for my bad english, i'm french
Today, i install Lion 10.7 on my compunter. All good but one things is wrong.
I can't mount any volumes, disk. Partition or Usb key NOTHING.
They say me "Impossible to mount the disk "nameofthedisk"".

In MSDOS, FAT32, FAT, exFAT nothing ...

If any body know a issue, it will be very nice.

Optional second problem:
My wifi card, a TL-WN851N don't work.
I think, i must install some kext, but i don't know how, and wich ?
