I've a similar problem. I checked the info about my usb pen drive with usbview:
I think the controller is MW6208 and I need UdTools 1.0.2.9.
The problem is these tools seem to be available only at a chinese site http://bbs.mydigit.cn/read.php?tid=4345, only members can download and to register you need an invitation code :(
I really want to get rid of this "automount cdrom" on my pen drive, can anyone provide me with the tools or an invition code?
Thanks in advance ;)
