thank you Tormod, the usb sniffer actually provided me with enough
information of what i needed. i was trying to configure the device through
the usb port, but what i'm getting from the IN endpoint is quite enough.

I will tell you the only thing that work for me, using wireshark. From knowing
the right commands you can start working properly.
Sorry for my english.

Hi all,
it's my first attempt with pyusb, and following the tutorial could not go
really further than "Let's get this started" section.
my device is a thermometer, it came with a software, and i can take
readings with the application included. however i'm trying to include it to
a python scripted

All I
This is the thing so far:
I cant get ctrol_transfer to work in anyway. It will always give an error.
Calling it even without payload:
# find our device
dev = usb.core.find(idVendor=TI_VENDOR_ID, idProduct=TI_3410_PRODUCT_ID)
dev.set_configuration()
# was it found?
if dev is No

It all depends on the device.
A C example here (sorry right now I have no pyusb example).

To use libusb
Thanks, but i am sadly confirming that this is not the error this time.
I have correctly detached it with:
interface = dev.get_interface_altsetting()
dev.detach_kernel_driver(interface.bInterfaceNumber)
which works, because "dmesg" logs it and the /dev/ttyUSB0 is released.
but in the error stag

For libusb-0.1

For lib

The point is, that running it as root i discard the usual questions,
"do you have the correct permissions?"
Yes, i have, and tripple checked

What do you
Hi people.
I am on the middle of an electronic project which handles USB throught
the device TUSB3410 which is a USB to serial converter.
The main problem of this device is the intense lack of documentation
and examples of how to program it.
Any way, researching a lot i found that the BSD project
12 matches
