Hi,
I have endless problems since upgarding to ubuntu12.04 with my usb
microscope and it's a big problem cos i need it for work.
As suggested in dmesg I have sent you the log.. Interestingly the
em2750 camera is Ok on my desk pc with Xubuntu 12.04... go figure.. But
the desk pC is kinda hard to carry to customer sites.
I hope to find a solution soon
thanks
Aaron
