Hi,
First of all I'm not sure this is a regression, but I'm afraid
I do not have time to dig deeper so I thought I should report
it anyways and then others can try to reproduce it.
I'm seeing the following happen when using a usb stick
with a musb-new otg controller in host mode on an allwinner
tablet:
sunxi# usb reset
resetting USB...
USB0: scanning bus 0 for devices... 1 USB Device(s) found
scanning usb for storage devices... error in inquiry
0 Storage Device(s) found
The interesting thing is that, the first "usb start" works
fine, this only happens on the second usb start (triggered
through a usb reset).
This may be specific to using musb on sunxi, or to the
flashdrive I have but I thought I should report this
anyways. Esp. since usb otherwise works fine after a
usb reset, other devices (usb keyboards) continue to
work, and the descriptors of the usb drive do get read
correctly:
sunxi# usb info
1: Mass Storage, USB Revision 2.0
- USB Flash Disk 4C0E960F
- Class: (from Interface) Mass Storage
- PacketSize: 64 Configurations: 1
- Vendor: 0x058f Product 0x6387 Version 1.3
Configuration: 1
- Interfaces: 1 Bus Powered 100mA
Interface: 0
- Alternate Setting 0, Endpoints: 2
- Class Mass Storage, Transp. SCSI, Bulk only
- Endpoint 1 Out Bulk MaxPacket 512
- Endpoint 2 In Bulk MaxPacket 512
Perhaps someone can test the reproducer on another board
with usb:
1) plug in a usb drive
2) do "usb start"
3) should print that 1 storage device is found
4) do "usb reset"
5) should still print that 1 storage device is found,
but for me gives the error I mentioned above.
Regards,
Hans
