Hey ItsJustMe, if you give me detailed instruction (with pictures or diagrams) and I am able to repair my broken iriver I am more than willing to attempt this mod.
Your instructions will have to be idiot-proof. (I am that idiot)
On the other hand I did successfully install the RTC chip so I'm not that bad. ;D
Looking forward to hearing from you! :)
GaardenZwerch:
I use a Y cable that a mini USB plug and a charger tip at one end and male USB plug on the other end. This works nicely for chargin on my Desktop. However, one day I had both USB and power plugged into my IHP 120. When I plugged the other end into my laptop, it just switched off. I haven't really tried to reproduce this since, because I'm not too keen on frying the USB port in my laptop, or even the laptop itself.
So I would rather not have this mod inside my Iriver... with the cable I can either 'just charge' or 'just plug USB' if I'm not sure the USB port can handle the current that is drawn. Additionnally, I wouldn't want to be charging each time I plug in... I like to let my batteries come 'close to empty' before charging them. I still believe this enhances their overall lifetime a bit...
Hope this helps you decide wether you want to try this mod
Have a nice day,
Frank

If I could charge from the USB cable I'd be willing to even remove the DC in jack, although I don't really understand why this would be necessary. As long as I didn't plugin both USB and DC in at the same time it should be OK right?
Am I missing something? (it wouldn't be the first time)
roolku:
The point of this mod is to use the built-in USB charging functionality of the BQ24022 which for some reason is not utilised on the h1x0. The chip takes care of how much current is drawn from the USB port and is perfectly save to use.
It is not comparable to the cable 'hack' GaardenZwerch uses.
Davide-NYC:
That's what I suspected but didn't want to presume anything since I have little expertise in this particular field.
@ anyone that knows their stuff:: Post instructions and I'll attempt this on one of my H1x0s in the name of Rockbox!
