Virtualbox with DE10-Lite USB Scan Problem

[GRAVE2]

I'm running Ubuntu 18.04 with Virtualbox and extensions running with Centos 6 virtual machine. Quartus Prime 18.1.0 is installed and working, and I have worked through several labs in the "4 Hour FPGA Course".

The lab where the USB Blaster is connected is where I am stuck.

The host machine is Linux Ubuntu 18.04. I had to add group vboxusers. Also configured the Centos machine with USB; Altera USB-Blaster is added.

Within the Centos vm from lsusb:

Bus 002 Device 002: ID 09fb:6001 Altera Blaster

From the host side (Ubuntu) this command:

VBoxManage list usbhost

Altera USB Blaster is "captured".

Using the Tools -> Programmer, I see:

USB Blaster variant [2-1]

So Quartus can see the DE10-Lite board via USB.

Clicking "Auto Detect":

Unable to scan the device chain. Please check the hardware setup.

All looks good to me. Any ideas?

Regards,

Greg

Found the USB bus was read only. Changed it:

chmod 666 /dev/bus/usb/002/002

The bus and device numbers in path above found with lsusb inside VM.

Hi Greg, I found almost similar issue on the following forum link. However, this user used usb-blaster II. https://forums.intel.com/s/question/0D50P00003yyT9pSAE/de1soc-dev-kit-trouble-w-usb-blaster-ii-centos7 Since you already found the solution, it’s good for Intel FPGA communities here to know this workaround. Thank you Greg. Regards, Shafiq
