UBUNTU 18.04 and USB disconnection

[gawrcool]

Hi,
I bought the CYC1000 from arrow and I downloaded their driver for linux(64).
I'm facing a problem with the FTDI Serial Device:
Here is the dmesg output:

Code Select Expand

<[36809.287957] usb 1-5: new high-speed USB device number 12 using xhci_hcd

[36809.480263] ftdi_sio 1-5:1.1: device disconnected

As you see the serial device is attached to ttyUSB0 but get disconnected after a few millisec (last 2 lines).
Anyone has an advice for this?
Regards,
Olivier

Hi,

did you test with other USB-cabel or on other USB Port on your host PC?

Is your OS native or VM?

Do you have annother PC to try out? Maybe with Win OS?

Hi John,
I looked at the rules from the arrow driver and I commented the last line, then it's Ok now.

# Arrow-USB-Programmer
SUBSYSTEM=="usb",\
ENV{DEVTYPE}=="usb_device",\
ATTR{idVendor}=="0403",\
ATTR{idProduct}=="6010",\
MODE="0666",\
NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}",\
RUN+="/bin/chmod 0666 %c"

# Interface number zero is a JTAG.
SUBSYSTEM=="usb",\
ATTRS{idVendor}=="0403",\
ATTRS{idProduct}=="6010",\
ATTR{interface}=="Arrow USB Blaster",\
ATTR{bInterfaceNumber}=="00",\
# RUN="/bin/sh -c 'echo $kernel > /sys/bus/usb/drivers/ftdi_sio/unbind'"

I don't know why this line is there !

Ty for your suggestion.
Olivier

Hi,
good to hear that it works now. I will forward your notes to arrow, so they can fix this in a future update
