I am experiencing a similar problem as described there: Whenever I connect my HTC One to my Windows 8.1, it is recognized as a CD Drive. So I tried the solution proposed by Macha's answer, but I cannot perform the step "Select Standard USB main controller" as I get only CD-Drives proposed int he selection no matter what.
Does anyone here have a hint how to solve the issue?
I tried to deactivate/activate USB Debugging without any success, but noticed, that whatever I select, the MTP still keeps running (at least my HTC says so). Furthermore I realized that in the device manager I see the "HTC Android Phone USB Device" in DVD/CD-ROM drives section and "MTP" in "Other Devices". Tried to update the drivers - either cannot find any appropriate drivers or does not change anything. Tried to disable MTP -> phone is not anymore connected as CD, but cannot see it in Explorer at all anymore.
Though, I cannot find any options to disable MTP. With my previous laptop (Windows 7) everything worked properly.
Does anyone have an idea how to solve the problem and again be able to see the phone as a storage device, access it, and to synchronize/exchange data with the PC back and forth?
Thank you so much in advance!
