Hello,
I'm new in this list and in driver's world.
My sister have a Philips HDD 1620 device. Its a mp3 device
with 6GB of storage space and it's no a standard usb device because
it doesn't work with the linux/mac/windows standard usb drivers. To
comunicate with the device it's supplied a plugin for the WMedia
player 10. The device box is marked with the PlayForSure logo.
But at home my main systems are Linux and Mac. So I'm
trying to make it work in Linux.
I started plugin the device to my linux box and I obtained
this message:
[17193362.540000] usb 1-1: new full speed USB device using uhci_hcd
and address 2
Then looking in /proc/bus/usb/devices I saw:

Ok, the device was detected but nothing happened.
Downloading the kernel sources 2.6.15 and reading some code
I found the file drivers/usb/storage/unusual_devs.h.
I tryed to add this:
UNUSUAL_DEV( 0x0471, 0x014c, 0x0000, 0x9999,
"Philips",
"Philips HDD14XX GoGear",
US_SC_RBC, US_PR_CBI, NULL, US_FL_BULK32),
and tryed to change various times the flags param and never
worked,

but whatever the flag was I allways obained the same error
[17179772.468000] usb 1-1: can't set config #128, error -32
I've seen that this error is thrown in the hub.c file,
concretely in the usb_new_device(usb_device) function. It calls
usb_set_configuration(usb_device, configuration) at messages.c. I
think the first thing that this function does is check that the
configuration received is in the usb_device structure. This
configuration is not found in the structure so the error is thrown.
By the data in /proc the configuration trying to assign is
the correct one.
When choosing the configuration in hub.c we used the same
structure than when setting the configuration in messages.c so I
don't understand how it could'nt find the configuration selected
before. As is seen in proc the device is informing correctly the
number of configurations (one).
Can somebody give me some light please!
Do you think it's possible to make this device work?
Thanks in advance!!!
