call op_detach_kernel_driver(linux_usbfs.c) failed, return -1, and errno= 113

[pengxianheng-nreal]

when I call op_detach_kernel_driver on Android, It‘s failed， and logs :

12-22 16:26:11.091 15259 15790 E libusb : [10.626199] [00003dae] libusb: error [op_detach_kernel_driver] detach failed error -1 errno 113

and later ,I call submit_control_transfer also failed. error is alose 113.

what does 113 errno means?

I can not find errno = 113 for libusb. Maybe it is from the lower level. And it seems to me you are not using an official version of libusb. Please use libusb-1.0.26 release or libusb-1.0.27-rc1 (recommended) or git and try again.

What is the Android device you are testing with? Is it rooted? Do you have the right permission if you use official version of libusb release (1.026 or 1.0.27-rc1) or libusb git.

Or better you may want to give PR #1164 a try to see if that helps.

@mcuee The libusb library I used is forked with this github 4 years ago.
I use the Android Galaxy S23. It's not rooted , and we get fd from android java (UsbManager, getFileDescriptor), and has right permission for my usb device. On other android phone, My usb devices and my app can work fine. On Galaxy S23,It's failed.

I see. In that case, the error codes may come from Android. Please check.

Unfortunately I can not help you much here as I have zero experiences with Android. I feel it is a problematic platform to support especially since the libusb main line is not working well and people have to use a fork.

Reference: there are multiple open issues for Android.
