Error transferring command; errno 0 null #275

I have a removable hard drive, which has two partitions, a public partition and an encrypted partition (unlocked with fingerprints). When the hard drive is plugged into the android phone, the call to API,device.init (), in libaums will always be unsuccessful. Is there any way to ignore encrypted partitions in init () and only init () public partitions?

Log when device.init () is called :

It looks like it is not trying to read the encrypted partition but has problems with the regular one.

Can you try the libusbcommunication module?

How to do some things with libusbcommunication module, such as getRootDirectory ,listFiles, file.getName?
