I never had any problems but after installing Rockbox today, (and all of that went fine, it works properly) and trying to connect it to my laptop again with USB doesn't work. Normally when you connect your H10 to a USB port..you heard a short sound...but i hear that sound twice now....i have had exactly this problem with my mobile phone's USB thing awhile ago. I would connect it to USB and it would just not show up in Vista at all.
I had to disable an certain USB option in the phone and it worked again...but i can't find anything about USB in the H10. I also tried removing the battery to reset it, but it doesn't help....all of the sudden Windows Vista is not seeing my H10 anymore......i've skimmed through the manual of Rockbox several times...but without any luck.
