UBUNTU 18.04 and USB disconnection
« on: July 09, 2019, 05:08:25 PM »
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]
<[36809.287957] usb 1-5: new high-speed USB device number 12 using xhci_hcd
[36809.440371] usb 1-5: New USB device found, idVendor=0403, idProduct=6010, bcdDevice= 7.00
[36809.440376] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[36809.440380] usb 1-5: Product: Arrow USB Blaster
[36809.440383] usb 1-5: Manufacturer: Arrow
[36809.440387] usb 1-5: SerialNumber: AR2EEYXG
[36809.444376] usb 1-5: Ignoring serial port reserved for JTAG
[36809.446352] ftdi_sio 1-5:1.1: FTDI USB Serial Device converter detected
[36809.446406] usb 1-5: Detected FT2232H
[36809.446588] usb 1-5: FTDI USB Serial Device converter now attached to ttyUSB0
[36809.480243] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[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.
Quote
# 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
