[Bug 1910605] [NEW] qemu-arm-static ioctl USBDEVFS_BULK return -1 (EFAULT) Bad address

[Linh Hoang]

Public bug reported:


Snippet of code sample:

struct usbdevfs_bulktransfer Bulk;
Bulk.ep = hUsb->UsbOut;          
Bulk.len = Len;          
Bulk.data = (void *)pData;          
Bulk.timeout = Timeout;
Bytes = ioctl(hUsb->fd, USBDEVFS_BULK, &Bulk)

The above code sample return -1 (EFAULT) Bad address when using qemu-
arm-static but is running ok when on qemu-aarch64-static.

I use a 64-bit intel laptop
