Hi

i wrote a shell script(bash, debian), using ifuse to mount iphone4(A1332) in script always got message: I/O error when copy file (no matter --container or --documents) this happen only in iphone4(other my 3 iphone4 got the same error )

but iphone4 in command line , mount and copy file is OK

the same script in iphone4s is OK .

ifuse version 2014/3/2 libfuse 2.9.0

I wonder the bandwidth of usbmuxd.

Since I test my ifuse mounting script independently and it'w work but I bundle the script in my project and it's not work(I/O error when copy file ,and only in iPhone4) There is some tcp forwarding communication in my project parallel working with the ifuse
Am I right about my assume? If true, and any suggestion?

P.S. I also test my project script in iPhone3GS and it's work

sorry my english, I hope you guys understand my description ^_^
