USB Stick Plugin for Total Commander (Android)

If you have an Error please report it here.

I havean 8gb sdhc card which is plugged into my Nexus10 via a Dane Elec usb device. Nexus Media Converter works with this so I know the hardware is ok.

your driver gives this error (latest version)

Initialising USB stick failed. Class de.hechler.tcplugin.usb stick.f.g: read capacity failed:-1


I can be contacted at alan (at) manhoc (dot) co (dot) uk if you want me to do anything

There are a number of Linux error reports with "USB read capacity failed".
Solution seems to be to use the same initialization sequence as Windows does.

Tested Micro SD USB Card Reader "Vartis Micro SD Card Reader" with a 2GB card without problems.
So I am not able to reproduce the problem locally.

Nizarel09 reportet problems with two SanDisk usb sticks.
The problem was, that both sticks have the U3 feature.

I found a Toshiba 1GB U3 stick to reproduce the behaviour.

Technically U3 sticks have two logical units (volumes),
one as mass storage device and one as cd-rom to start the autostart launcher.
Currently the plugin takes the last lun which was accidentally the CD-ROM.

As a FIX the plugin now iterates over all LUNs and queries for the "Peripheral device type" (see inquiry command http://en.wikipedia.org/wiki/SCSI_Inquiry_Command).
The CD-ROM has "Peripheral device type" = '5', where the mass storage device has "Peripheral device type" = '0' (see http://en.wikipedia.org/wiki/SCSI_Perip ... evice_Type).
The first mass storage LUN will be used.

The FIX will be published in the free version first to prove functionality.

I have installed the latest Total Commander ( 2.03 Beta) and the latest Beta USBstick plugin

I have a Nexus 7 (2013) unrooted

The OTG cable works fine with a mouse

I have tried with various USB sticks - all FAT32 formatted

All I get is "reconnecting to USB stick..." and nothing further
