plz help - s1mp3 scd034 rev.5

hey
I've searched for some time for the answer in sites and datasheets but...
anyone knows how to fix a scd034 rev.5 that doesn't work at all when connected to usb (on battaries it works fine)?

another unit from the same device I have, started to be sensitive to the environment (self shutdowns , flickering , destroying data) up to reformatting - only when powered by battaries

thanx

Probably it is a physical problem. Try another cable, another computer then another cable with another computer. If this doesn't help the only solution I see is to open the device and see if some contacts are broken. Those would have to be soldered.

Hey again
Since I'm dealing with my problem in my free time - it took me a while to find something resembles to an answer

I've found on this site a connection scheme and found that if I short-circuit on resistor R1 than problem solved!
The resistor is fine and any side of it is connected - but as a whole it doesn't work
I havn't fixed it yet because I'm afraid that the cpu now gets too strong signal, and I'm checking my options

Do any of you think of another solution?
Any comments will be appreciated
