Error on synology

[koen01]

I get an error when trying my blinkstick on a Synology D213j. See the python error below; Dmesg shows this: [366402.501085] usb 1-1: new low-speed USB device number 3 using ehci_marvell [366402.742338] Get empty minor:104 [366402.764126] generic-usb 0003:20A0:41E5.0002: hiddev0: USB HID v1.01 Device [Agile Innovative Ltd BlinkStick] on usb-ehci_marvell.0-1/input0

Any ideas as to resolve this?

Does it have libusb installed?

[koen01]

I think it does, there are libusb.so files in /lib/ Op 25 mrt. 2014 22:11 schreef "Arvydas Juskevicius" < [email protected]>:

[koen01]

I just got home and libusb is installed and the blinkstick is detected by libusbtest: DiskStation> ./testlibusb Dev #1: Linux 3.2.40 ehci_hcd - Marvell Orion EHCI Dev #1: Linux 3.2.40 ehci_hcd - Marvell Orion EHCI Dev #2: Agile Innovative Ltd - BlinkStick

Does this give you any idea in which direction to look? I hope it's just not kernel related... Maybe pyusb?

[arvydas]

It's something related to pyusb as it's complaining that it can't find is_kernel_driver_active function. What version of Python and what version of PyUSB do you have installed?

[koen01]

Python 2.7.3 pyusb 1.0.0b1

i reinstalled blinkstick, pyusb and libusb, and now get the no backend error.. but the mac os fix doesn't seem to work on synology.

I have libusb symlinks in /lib/ /usr/lib/ and /usr/local/lib/ is there a env variable perhaps that is wrong/missing?

[arvydas]

@koen01 can you please check if this issue still persists with the latest version of BlinkStick library for Python?

[arvydas]

Closing this as I haven't heard back

[koen01]

Yeah sorry, am away on travels for 4 weeks sorry Op 3 okt. 2014 20:11 schreef "Arvydas Juskevicius" <[email protected]

No problem. Just let me know if it's still an issue and I will reopen.

Hey,

looks like the same or similar issue on a RaspberryPi (mode b+)

    raise NotImplementedError(func.__name__)
NotImplementedError: is_kernel_driver_active

Installed stuff by following http://www.blinkstick.com/help/raspberry-pi-integration

What more debugging info can I provide in order to solves this?

[arvydas]

I have a B+ model. Will test this and will let you know. What OS are you using with RPi?

[fxlv]

It runs Raspbian 7.6 and BlinkStick control script 1.1.4

[arvydas]

Thanks for the info.

Hello, just got my BlinkStick and I'm experiencing the same issue under debian wheezy, with the latest BlinkStick library (1.4) and libusb 1.0.0 :-(

@gfountis I managed to reproduce it, looking for a solution now. Will let you know when as soon as I have one.

[arvydas]

There seems to be a regression in PyUSB 1.0.0b2 on some Linux based operating systems, downgrading to b1 should solve this issue.

If you already have BlinkStick Python package installed, please run the following commands:

sudo pip uninstall -y pyusb
sudo pip install pyusb==1.0.0b1

If you don't have BlinkStick Python package already installed on the system, run the following commands:

sudo pip install pyusb==1.0.0b1
sudo pip install blinkstick

Test by running the following command:

sudo blinkstick --info

If you don't want to run BlinkStick command script with sudo, please follow these instructions:

https://github.com/arvydas/blinkstick-python#permission-problems-in-linux-and-mac-os-x

I will try to find a solution to permanently add a workaround for BlinkStick pip package.

[gfountis]

Thanks alot arvydas! it's working now :-)

[arvydas]

@gfountis thanks for letting me know :-)

[Conan-Kudo]

@arvydas is this still an issue with pyusb 1.0.0rc1? It was recently released and it'd be good to know if it's still an issue...
