 |
|
hi all,
yet another problem that is driving me nuts 
got myself an HanfTek USB DVB Stick. should be supported fine:
http://linuxtv.org/wiki/index.php/DVB_USB#HanfTek_UMT-010
if i plug the stick in, the modules are loaded:
| Code: |
dvb_usb_umt_010 7680 0
dvb_usb_dibusb_common 9284 1 dvb_usb_umt_010
dib3000mc 15872 1 dvb_usb_dibusb_common
dib3000_common 3072 1 dib3000mc
dvb_usb 22216 2 dvb_usb_umt_010,dvb_usb_dibusb_common
dvb_core 89712 1 dvb_usb
dvb_pll 16836 3 dvb_usb_umt_010,dvb_usb_dibusb_common,dvb_usb
mt352 8132 1 dvb_usb_umt_010
|
dmesg output:
| Code: |
usbcore: registered new driver dvb_usb_umt_010

well, doesnt look bad sofar, right? however, there is no such /dev/dvb 
i came across a few older threads in this forum, and even added local rules like this:
20-local.rules:
| Code: |
KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
|
not sure if this is even needed, because 50-udev.rules already contains a dvb rule. well, anyway, the dvb devices are not created here.
OTOH, other sticks (memory stick aso) are detected fine!
what could this be? i am at a loss 
looking at the kernel documentation in /usr/src/linux/Documentation/dvb/udev.txt it says:
[quote]
We assume that you have udev already up and running and that have been
creating the DVB device nodes manually up to now due to the missing sysfs
support.
[/code]
no, i did not create the DVB devices manually, how should i do this? should i do this at all?

DocReedSolomon,
There is some good news and some bad news ... some of these devices are supported and some are not.
Please post the Vendor and Device IDs from lsusb, or from /proc/bus/usb/devices.

oops, i already did?
| Code: |
dvb-usb: found a 'Hanftek UMT-010 DVB-T USB2.0' in cold state, will try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-umt-010-02.fw'
|
lsusb for sure displays this likewise:
| Code: |
Bus 002 Device 009: ID 15f4:0025 HanfTek HanfTek UMT-010 USB2.0 DVB-T (warm)
Bus 002 Device 001: ID 0000:0000
|
but why arent my devices created? damn
/proc/bus/usb/devices:
| Code: |
T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 9 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

DocReedSolomon,
Looking at the kernel driver /usr/src/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h, it doesn't know your device.
That file contains | Code: | | #define USB_VID_HANFTEK 0x15f4 |
so the Vendor ID is good and | Code: | #define USB_PID_HANFTEK_UMT_010_COLD 0x0001
#define USB_PID_HANFTEK_UMT_010_WARM 0x0015 |
Your device has a deevice ID of 0x0025, so that driver doesn't know it and will not bind to it.
Do you feel lucky ?
Change the 0x0015 to 0x0025 so the driver will bind to your device. Rebuild and reinstall your kernel to use the modified code.
If thats all it is, it will work. If its really a different device, you will be no further forward.
Should your luck be in, please file a bug at bugs.gentoo.org so that the kernel gets updated and it JustWorks for you and everyone else in future.

well, after changeing this, i didnt even get it to warm sate at all. also still no devices in /dev.
googleing around a bit i meanwhile found a few mac users, they didnt get the stick to work either.
probably just a cheap clone (yes, made in china). i will give it back later this day.
thanks for your help!
and anyway, it is supposted to work in win XP. infact it doesnt work there either.. |
