[BUG] Unable to use light on Windows #87
Comments
|
This is a duplicate of issue #56 unfortunately. I wrote BusyLight with the assumption that files are generally opened with exclusive access (meaning the file gets opened once and successive opens fail until the file is closed). The entire light discovery strategy hinges on this behavior, which Windows does not honor. This will remain broken until I have time to fix it or someone kindly contributes a fix. |
|
My bad - I did not read #56 as the title did not hint at the same issue. I will play a bit around if I can get it to work using Python in WSL2 (Debian 11) on the same machine - maybe it does something differently when inside the de-facto WSL VM. |
|
Knowing more people are interested in using it on Windows helps motivate me to fix it, thanks for the bug report. I'm curious if WSL has the same problem (I suspect it does not). |
|
Indeed - it works! Followed instructions from https://devblogs.microsoft.com/commandline/connecting-usb-devices-to-wsl/ , installed usbipd-win from https://github.com/dorssel/usbipd-win/ (also available via Windows packet manager), attached the USB device to the WSL-VM: dmesg shows it nicely: and does exactly what it was intended to do - controls the light nicely. However, found an 2 errors in debug output when calling I believe USB devices are kind of pass-thru to the (under-the-hood) Hyper-V based VM, but directly on (raw) device level. Your code - resp. Python - seems to work on one abstraction layer higher, "device control level". That name might be completely wrong, but I hope you get what I'm trying to convey. |

Thank you for the report that it works on Windows from within WSL. The "errors" in the debug output are expected, as you surmised. |
|
Windows tests as of version 0.22.2 are passing, indicating that the change in software architecture might have benefited Windows users. Any reports good or bad for this latest version on Windows? |
|
On Windows with busylight v0.26.0 the devices are correctly detected but nothing happens when I try to set a color, the device light is still off. Note I tried on MacOSX and I works fine. |
This is the interesting part of the debug output, both writes to the Blinkstick Square devices failed "wrote -1" and the flag write succeed with a 9 but the command word is seven bytes (I think there is a 0x0000 prepended which would bring it up to nine bytes, I have to go back and look at the code). @remss if you have some time and are willing, could you try running this fragment in a repl? from busylight.lights import Flag
l = Flag.first_light(exclusive=False)
l.on((0,255,0)) |
|
Here the result, and the light of the Luxafor device is still off |
|
Well, darn. Until I have a windows machine to debug on (or someone submits a patch) this is going to stay broken for now. We could try to verify that import hid
device = hid.device()
device.open(0x04d8, 0xf372)
device.write([ 0x1, 0xff, 0, 0xff, 0, 0, 0]). # cmd, leds, red, green, blue, fade, repeat
# flag should be on with a green color |
|
The hidapi is working well, the light comes green (I had to change a little the data to send, an initial 0 was missing) My 2 cents about Windows machine,: you might use VirtualBox and prebuilt images from https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ |
|
That is odd. AFAIK the first byte in the Luxafor instruction buffer of eight bytes is a command whose valid values are 1, 2, 3, 4, and 6. Also there are only eight items in the list you passed to |
|
I'll have a windows machine to test on in the near future, I guess stay tuned. >>shudder<< |

Hi, was not sure if it was best to add to this on #56 or here but I would like to say that the problem is also happening with Win 10 under python 3.7. and 3.11. busylight.lights.hidlight:available_lights:50 - Flag found 1

Hey this is still broken, I have Kuando Busylight Alpha and while the program seems to pretend to be doing something, nothing happens on the light itself. |
|
Hi @Gunni, no new progress has been made on getting Busylight working in the Windows environment. My plans for a Windows development machine have not yet come to fruition. |

Just received a Kuando Omega today and was hoping to play around with it a bit using your repo. Then I found this issue :( Any chance to control the Omega using hidapi in Python? I built this and using it I'm able to open the device but the report message does nothing. Any help is appreciated. import hid
import time
device = hid.device()
device.open(0x27bb, 0x3bcf)
def set_light_on():
report = [0x00, 0x01, 0xFF, 0x00, 0x00, 0x00]
device.send_feature_report(report)
def set_light_off():
report = [0x00, 0x00, 0x00, 0x00, 0x00, 0x00]
device.send_feature_report(report)
set_light_on()
time.sleep(1)
set_light_off()
device.close() |

With the help of Claude 3.5 I've built this. I don't really know what I'm doing here (sysadmin, not a dev) but this code looks more up to the spec I've found in this repo. Anyway, still getting no light. import hid
import time
import struct
# Vendor/Product ID des BusyLight Omega
VENDOR_ID = 0x27bb
PRODUCT_ID = 0x3bcf
# Funktion zum Berechnen des Checksums
def calculate_checksum(packet):
return sum(packet[:62]) & 0xFFFF
# Funktion zum Erstellen eines Jump-Befehls
def create_jump_command(red, green, blue, on_time=0, off_time=0, repeat=0):
command = [0] * 64
command[0] = 0x1 # JUMP_OP
command[1] = 0x0 # target
command[2] = repeat
command[3] = red
command[4] = green
command[5] = blue
command[6] = on_time
command[7] = off_time
command[62] = calculate_checksum(command) & 0xFF
command[63] = (calculate_checksum(command) >> 8) & 0xFF
return command
# Funktion zum Erstellen eines Keep-Alive-Befehls
def create_keepalive_command(timeout=15):
command = [0] * 64
command[0] = 0x8 # KEEP_ALIVE_OP
command[1] = timeout
command[62] = calculate_checksum(command) & 0xFF
command[63] = (calculate_checksum(command) >> 8) & 0xFF
return command
# Hauptfunktion zum Steuern der BusyLight
def control_busylight(red, green, blue, on_time=0, off_time=0, repeat=0):

# Erstelle und sende den Jump-Befehl
jump_command = create_jump_command(red, green, blue, on_time, off_time, repeat)
device.write(jump_command)

except Exception as e:

finally:

Software Versions:
General Type of Problem
Describe the Problem
USB-connected Embrava BLYNC USB 30s.
Command line parameters "list" and "supported" never return. Debug output shows endless loop of iterating over same device.
Any control command hangs as well, does not control the light and never returns.
Same behavior running with and w/o admin-privileges.
Having installed Embrava Software does not change behavior.
Expected Behavior
Listing compatible resp. supported device, in my case Embrava BLYNC USB 30s
Error Output
