recently I had removed my internally installed Liteon SOHR-5239V CDRW drive, that is now connected to an USB/IDE adapter with Myson Century chipset.
Befor that, I was able do scan my discs with Kprobe and CD/DVD Speed. Now, scanning with CD/DVD speed does not work any more with that drive, but Kprobe does.
There is no general problem with USB connected drives, as my USB-connected SHM-165P6S (Cypress based enclosure) works fine with both applications.
Any ideas explaining, what happened are very appreciated.
