Is there Digi transport support for USB to TCP/IP socket like with the serial port?

Digi TransPort WR (Series)

Wondering what kind of support there is for USB to TCP/IP support on the Digi transport routers.

Cheers,

“Depends”. What are you wanting to plug into the USB port?

The USB ports can be used for mass storage devices (USB keys/external hard drives) or serial devices based on Prolific or FTDI chipsets (serial adapters/GPS adapters/TTL adapters).

If it is a serial device plugged into the USB port then you can do the same as you would for a fixed serial port.

What would the TCP port number be in that case?

Well first you would check it enumerates with the “busb show” command
ss325999>busb show
BUSBcmd
BUS 1
dev:1 (usb) depth:0 Marvell EHCI root hub (HUB driver)(ports:1)
dev:2 (usb-1) depth:1 vendor 0x0424 product 0x2514 (HUB driver)(ports:4)
dev:3 (usb-1.1) depth:2 Sierra Wireless, Incorporated MC7710 (UMSM driver)(QMI driver)
dev:
dev:
dev:4 (usb-1.4) depth:2 FTDI USB HS SERIAL CONVERTER (UFTDI driver)
OK

Then you would see what the matching asy port is with the “asydevs” command:
ss325999>asydevs
ASY 5 assigned to usb-1.1 interface: 3
ASY 6 assigned to usb-1.1 interface: 0
ASY 7 assigned to usb-1.1 interface: 2
ASY 8 assigned to usb-1.4 interface: 0
ASY 9 unassigned
ASY 10 unassigned
OK

Then you can telnet to port 4008.

You should to lock these configurations so the asy ports dont change over a reboot.

Hi Nicholas:

I plugged in my device and it looked like this:
ss398837>busb show
BUSBcmd
BUS 1
dev:1 (usb) depth:0 Marvell EHCI root hub (HUB driver)(ports:1)
dev:2 (usb-1) depth:1 vendor 0x0424 product 0x2514 (HUB driver)(ports:4)
dev:3 (usb-1.1) depth:2 HUAWEI Technology HUAWEI Mobile (CDCE driver)(UMSM driver)
dev:
dev:
dev:4 (usb-1.4) depth:2 TRIMBLE Instrument-Mgr
OK

ss398837>asydevs
ASY 5 assigned to usb-1.1 interface: 2
ASY 6 assigned to usb-1.1 interface: 3
ASY 7 assigned to usb-1.1 interface: 4
ASY 8 unassigned
ASY 9 unassigned
ASY 10 unassigned
OK

It looks as though the WR44 doesn’t know what to do with the usb-1.4.

What are your thoughts?

Cheers,
John

That means that there is no driver loaded which means the product is not built on a FTDI or Prolific chipset.
