The device(mobile) works in two modes(one at a time): as a CDC device and Memory Stick But for the testing of phone features the device should always be detected as a CDC device. =20 Initially if the device is in phone mode, and if we reset the device, after reset it is being detected as a Memory Stick. Is there any way to bring the device back to phone mode through software(without physically handling the device). This is required since the testing will be done remotely. =20 Any help in this regard will be highly appreciated. I will be pleased to provide any information required. =20 Below is the output of /proc/bus/usb/devices when device is in different modes: =20 -------------------------------------------------------------------- Phone mode -------------------------------------------------------------------- T: Bus=3D04 Lev=3D02 Prnt=3D80 Port=3D00 Cnt=3D01 Dev#=3D 87 Spd=3D12 = MxCh=3D 0 D: Ver=3D 2.00 Cls=3D02(comm.)

The obvious suggestion would be to use usb_set_configuration(): http://libusb.sourceforge.net/doc/function.usbsetconfiguration.html I have already tried usb_set_configuration(), but it gives an error, an invalid argument.=20 but given that "#Cfgs=3D1", the device may not support switching configurations remotely. The configuration number could be essentially read-only (for matching drivers in another OS, for instance). Yes, at one time, only one configuration is being listed.=20 -- - Charles Lepple ------------------------------ Message: 3 Date: Thu, 24 Aug 2006 17:18:57 +0200 From: Peter Stuge <stu...@cd...> Subject: Re: [Libusb-devel] changing USB device mode To: lib...@li...

You should ask SE technicians for a definitive answer on the recommended way to do so. Meanwhile you could try "soft detach" - disabling the hub port that the device is connected to and then re-enabling it. I'm not sure the Linux hub driver can do this currently, but it would probably be easy to add an ioctl for it. I mentioned after resetting the device, the device is detected as Memory stick. Actually in device reset we follow the following steps: 1)Disable hub port power (to disable charging of the device) 2)Remove battery charge 3)Put the battery charge back 4)Enable hub port power ( enable charging) So the above steps involve soft detach. After all the above steps I tried the soft detach process again. But still the device is detected as Memory Stick. //Peter ------------------------------ ------------------------------------------------------------------------ - Using Tomcat but need to do more?
