Hello,
I picked up an old 4GB Sansa Clip v1 recently. (I assume it's a v1 since the system version comes up as V01.01.18A; it says BH0804ATWK on the bottom.) All the buttons and functions seem to work and it is properly identified when I plug it into the handy Windows XP (32-bit) machine I still have kicking around.
Unfortunately, when I plug in into my Windows 7x64 computer, it comes up as an Unknown Device, regardless of whether I try to switch it to MTP or MSC. This is all the more frustrating as my Sansa Clip+ works perfectly with Windows 7.
Is there some way of circumventing this problem? Will it help if I install Rockbox on the Clip v1? (Is that even still an option..?)
