Is the debug interface connected by USB? Then it is possible to setup an udev 
rule in order to allow non-root access. Copy a file to /etc/udev/rules.d, for 
the J-Link for example I named it 99-jlink_mse.rules, the content:
"
ACTION!="add", SUBSYSTEM!=="usb_device", GOTO="jlink_rules_end"
ATTR{idProduct}=="0101", ATTR{idVendor}=="1366", MODE="664", GROUP="users"
ATTR{idProduct}=="0102", ATTR{idVendor}=="1366", MODE="664", GROUP="users"
ATTR{idProduct}=="0103", ATTR{idVendor}=="1366", MODE="664", GROUP="users"
ATTR{idProduct}=="0104", ATTR{idVendor}=="1366", MODE="664", GROUP="users"
ATTR{idProduct}=="0105", ATTR{idVendor}=="1366", MODE="664", GROUP="users"
LABEL="jlink_rules_end"
"
"lsusb -v" lists the connected USB-devices with their device descriptor.
The file provided by Segger did not work because of an unknown BUS variable 
and SYSFS instead of ATTR.

I tried to connect an EFM32 board by openocd->J-Link->SWD->Chip, sadly the 
openocd J-Link driver supports JTAG only. :-(
