Can't connect LPC-Link1 dev board

I have an LPCXpresso LPC11U24 dev board which I can't get MCUXpresso to connect to.


I have previously had the board working on a different PC running LPCXpresso.


I am running on fresh install of Ubuntu Linux, a fresh MCUXpresso install 10.0.2_411 and a supported development board plugged directly into the PC.


The system recognises the board:

$ lsusb

Bus 001 Device 016: ID 0471:df55 Philips (or NXP) LPCXpresso LPC-Link


I can connect to it using dfu-util:

$ dfu-util -l
dfu-util 0.9

I can configure the device using boot_link1


$ ./boot_link1

I cannot, despite considerable fiddling get it recognised by the RedlinkServer

No probes found



Any suggestions for how I can connect to the board?
