What could be the reason for this? Is there anything I can try to distinguish between say a bug in the system or a hardware-problem of the stick (it’s a very cheap chinese one and unfortunately at the moment I only have one at hand so in theory it could be just this one bad stick…)
Is there anything I can do to mitigate this problem (using different files systems etc).
The problem maybe both openWrt driver or usb disk problem.
Do you mean you use amule in the in the mini router? That could be tough. Any more detail to replicate this issue. For example, how to set up amule in the router and which resource do you try to download.
