Some people reported problems with the DRiver resulting in a "Start Code 10 Error" on Win7 and Win8. I have no idea why that happens but Latif Berisha posted a link to another driver source in the comments (+1 him for that). For your convenience, this is his comment:
Mastadex supplied the following information: " +MNHS Beacon I did some digging and found that the CDM 2.04.16 driver can be used in place of the SmartTronik driver you posted. It appears to have fixed whatever was causing my BSOD earlier. I uploaded the driver here: https://anonfiles.com/file/67ad47aca3... (link not virus-tested, note by MNHS) Note that this driver is also WHQL certified and doesn't produce 'untrusted driver' warnings."
