Cool. However, could you also add a way to use/force the fastest charging mode in GTA02 (i.e. 1A charging)? -- Treviño's World - Life and Linux http://www.3v1n0.net/
How to switch usb mode to 500mA (enable USB charging with car charger) ?
Hi, I'd like to use a 12V USB car charger from my Wintec WBT201 for powering and charging the GTA02. the car device claims to be 500mA but I only get [EMAIL PROTECTED]:~# cat /sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/charger_type host/500mA usb mode 100mA is it possible to force charging and/or switch mode to 500mA by software (not soldering resistors to the cable etc) ? I found some rumors on the list that this might be possible but can't find any details... thanks, Harald -- I hope to die ___ _ before I *have* to use Microsoft Word., 0--,|/OOO\ Donald E.
