UsbFileOutputStream write operation limited to 500 bytes #351

Hi, If I try write to USB drive chunks with size more then 500 bytes, the stored data is corrupted. But if I divides data to chunks of 500 bytes, so copying file 8Mb from smartphone to USB drive takes more than 2 minutes. Why UsbFileOutputStream is limited to 500 bytes data?

Are you using the example app? The example app is using a bigger buffer size I think. Never had probelms with that tbh.

Does the example app work properly for you?
