hi there i am wonder if any might have knowlege on why i can not get NCS2 to work on a hotplug platform( openwrt router - intel based ) I can get openvino to work with cpu and gna . just not MYRIAD.
i wrote a hotplug script to emulate udev but does not seam to work - i know you have 3 entries in your myriad rules but one entry never shows up so i can not determine the version number so I think it for a different device .
```
#!/bin/sh
echo "${PRODUCT}" >> /tmp/usb_add
#fi
ncs2_PRODID="3e7/2485/1"
if [ "${PRODUCT}" = "${ncs2_PRODID}" ]; then
if [ "${ACTION}" = "add" ]; then
# echo "usb added highspeed" >> /tmp/usb_add
if [ -z ${DEVNAME} ]; then
echo "transistion" #>> /tmp/usb_add
else
echo "usb added highspeed" >> /tmp/usb_add
chmod 666 /dev/${DEVNAME}
echo "/dev/${DEVNAME}" >> /tmp/usb_add
# echo "setting prmission" >> /tmp/usb_add
fi
#
fi
fi
ncs2_PRODID="3e7/f63b/100"
if [ "${PRODUCT}" = "${ncs2_PRODID}" ]; then
if [ "${ACTION}" = "add" ]; then
# echo "usb added superspeed" >> /tmp/usb_add
if [ -z ${DEVNAME} ]; then
echo "transistion" #>> /tmp/usb_add
else
chmod 666 /dev/${DEVNAME}
echo "usb added superspeed" >> /tmp/usb_add
echo "/dev/${DEVNAME}" >> /tmp/usb_add
# echo "setting permission" >> /tmp/usb_add
fi
#
fi
fi
```
and it switching permission on device when it switches from high speed to super speed device. ( some part of the code is just debugging info)
and this is the output i get from benchmark_app when running it
```
I: [ncAPI] [ 944074] [benchmark_app] ncDeviceOpen:926 ncDeviceOpen() XLinkBootRemote is running for 1.1.2-ma2480...
I: [ncAPI] [ 944305] [benchmark_app] ncDeviceOpen:944 ncDeviceOpen() XLinkBootRemote returned success X_LINK_SUCCESS for 1.1.2-ma2480

```
thank you for your time

add info:
you can see it booting the device; lsusb output:
```
Bus 001 Device 005: ID 214b:7000 USB2.0 HUB
Bus 002 Device 009: ID 03e7:f63b Intel Corporation VSC Loopback Device
Bus 002 Device 007: ID 05e3:0626 GenesysLogic USB3.1 Hub
```
and that the permissions are set
```
crw-rw---- 1 root root 189, 136 Jun 13 18:36 /dev/bus/usb/002/009
```
when I trace the device interactions on a ubuntu loaded computer . it appears identical. from what i can tell
the dmesg output
```
[31815.429909] usb 1-1.2: new high-speed USB device number 23 using xhci_hcd
[31941.185788] usb 1-1.2: USB disconnect, device number 23
[31941.443153] usb 2-1.2: new SuperSpeed Gen 1 USB device number 9 using xhci_hcd

[31954.553395] usb 1-1.2: new high-speed USB device number 24 using xhci_hcd
```
plus i forgot to mention it running in a chroot enviroment on openwrt. and other methods work such as cpu and gna . I have not tried GPU as it has a gen 8 intel video processor (N3160). I have an gen 9 N100 next week. the project is an all in one low power (~5w) in AI house controller. router/firewall/vpn/IDS , zigbeehub(zigbee2mqtt) automation(domoticz) database NAS . voice controlled AI. zoneminder and currently I wanted to add in video facial recognition at entry points hence the myriad device

Hi skrywenko,
According to Configurations for Intel® Neural Compute Stick 2, there are 3 rules in 97-myriad-sbboot.rules as follow.
SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="2485", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="f63b", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
Please try to include product ID,2150 as well.
Regards,
Peh

thank you for the reply Peh
would you know the bcdDevice # for ID 2150 it never pops up in dmesg whether running under openwrt or in ubuntu20.04 or 22.04
as I can not get hotplug to work with out knowing it
```

```
also this line in my hotplug.d script "echo "${PRODUCT}" >> /tmp/usb_add" prints every dev/bus/usb events . to a log file called usb_add.
example out put to usb_add

5e3/610/6205 is a usb device that was plugged in before the myriad device was plugged in
once the myriad is plugged in ->3e7/2485/1
3e7/2485/1 -> connected /detected
usb added highspeed-0 -> transition stage when no dev/bus/usb has being allocated
usb added highspeed-1 -> stage when /dev/bus/usb is allocated
/dev/bus/usb/001/022 -> the the setting of the permissions for MYRAID device (highspeed)
3e7/2485/1
usb added highspeed-0 -transition to prepare for super speed device
3e7/2485/1 ...
when MYRIAD device switches over to VCS loop back -> 3e7/f63b/100
3e7/f63b/100 -> connected/detected
usb added superspeed-0 -> transition stage when no dev/bus/usb has being allocated
usb added superspeed-1 -> stage when /dev/bus/usb is allocated
/dev/bus/usb/002/008 -> the setting of the permissions for VCS loopback device (superspeed)
3e7/f63b/100
usb added superspeed-0 -> detransitioning stage back to highspeed
at no point does ID,2150 on the USB bus display itself

Hi skrywenko,
Thanks for the clarification. Yes, product ID:2150 is not required.
To use MYRIAD plugin, please ensure that you download OpenVINO™ Runtime 2022.3 from the archive file and update the environment variables by running the setupvars.sh script before running Benchmark_app with NCS2.
Regards,
Peh
