I have connected the VBus/USB adapter to a Linux device and with a Python script I want to read out the data.
When I read the USB port (/dev/ttyACM0) with a Python script nothing is read:
c = self.vbus_ser.read(1)
The port is opened as follows (portstr is /dev/ttyACM0):
self.vbus_ser = serial.Serial(port=None, baudrate=9600, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, bytesize=serial.EIGHTBITS, timeout=5.0)
attempt = 1
# configure the serial connections (the parameters differs on the device you are connecting to)
try:
self.vbus_ser.port = portstr
while (self.vbus_ser.isOpen() == False) and (attempt < 5):
print "Attempt #" + str(attempt) + ", connecting to " + portstr
self.vbus_ser.open()
attempt = attempt + 1
if True == self.vbus_ser.isOpen():
print "Connected to " + self.vbus_ser.portstr
except serial.SerialException as e:
print e
attempt = 1
# configure the serial connections (the parameters differs on the device you are connecting to)
try:
self.vbus_ser.port = portstr
while (self.vbus_ser.isOpen() == False) and (attempt < 5):
print "Attempt #" + str(attempt) + ", connecting to " + portstr
self.vbus_ser.open()
attempt = attempt + 1
if True == self.vbus_ser.isOpen():
print "Connected to " + self.vbus_ser.portstr
except serial.SerialException as e:
print e
Are there any VBus/USB drivers needed for Linux? What can be the problem here? Any help would be appreciated.
Regards ,

Hi, you don't need drivers, you operating system has recognised the device and assigned a tty to it
Try from shell
Cat /dev/ttyacm0 | hexdump
You should see the data stream
I did write a small c utility to decode vbus that might do what your looking for? I updated recently with some more basic features

Hi Andy,
When I try cat /dev/ttyACM0 | hexdump from shell it doesn't result in any datastream. The result of this command is empty.
Any idea?

sounds like your not getting any data from the device. what device is it, what usb cable/interface are you using etc. etc.

It's a ZEN Dt5 controller which as a Deltasol BS device connected to a VBus/USB adapter to the USB port of a RaspberryPI.
I have used the same script on a Windows 7 PC (with the drivers installed from Resol and connected via the USB port to the VBus/USB adapter) and on that PC I can read the data.
So it is not clear to me why it is not working on a Linux device.

Can you send the output of dmesg? What distribution are you using for your pi?
I recall usb issues in some linux versions on pi, I don't remember which ones though
