I am running 11.2 64 bit on a Dell Vostro machine.
I am unable to get piklab to connect to a PICKit 2 over USB.
I have created a file /etc/udev/rules.d/26-microchip.rules which contains the line:
ATTR{idVendor}==“04d8”, ATTR{idProduct}==“0033”, OWNER:=“root”, GROUP:=“users”,MODE:=“0660”
This gives a node /dev/bus/usb/006/002 with attributes crw-rw---- owner root group user. The device is rear/write to any member of the “users” group.
In piklab the dialogue “Configure Piklab” reached through the menu Programmer->Settings… on the Preogrammer Selection the Port Selection tab displays USB Connection:Error.
After much research I find that there may be problems with the libusb library under 11.2 so I try to see what is returned by lsusb. I enter the command:
sudo lsusb -v -s 006:002
this returns:

cannot read device status, Broken pipe (32)
This shows that the udev mechanism appears to be finding the device and all the data is being collected but the last line looks ominous.
What does “cannot read device status, Broken pipe (32)” mean and where does it come from?
Is this the cause of the USB connection error?
Can anyone help please?
