The fun*****tal problem - not in JAWA-card or drivers, a problem in Card-readers. The supply voltage submitted on carts should be about 3.2 volts. Cheap Card-readers give hardly less than five volt. Lovering a supply voltage up to 3.2-3.8 volts completely solves all problems.
Starts to work and correctly to be identified on anyone USB, on Win-98, on anyone USB-hub!
Thus it is unessential to open Card-reader, it is enough to make an adapter in USB-connector, lowering a supply voltage cards up to 3.2-3.8 volts.

Today i add on cable card 5 volt from external power supply (i use 2 diode) and it not help for me.

Denis-hunter · 02-11-2004, 11:13

Also i install internal USB 2.0 card (InnoVision) - and it too not help for me.
I want to try card with external USB 2.0 HUB by D-Link.
But i think it is useless!

My card is working 100%! (On notebook P4-2 Ghz).

Change these 2 capacitors with 220-240pf can solve the problem for
some old PC or Notebook with USB1.0/1.1

I change capacitors to 220 pF - it working 200%.
It working on old USB 1.0 (on motherboard) and internal USB 2.0 card (InnoVision).
