What you say is not accurate. The USB100V2 is less than $100 and is plenty fast enough. The TinCan Tools just doesn¹t work and there are several users on this mailing list that have tried and failed. If you are using Starterware, CCSV6 makes software development really easy because you can edit, compile, download to the BeagleBone and then you are given diagnostic tools to view thread execution, code coverage, timing metrics, etc. While the USB100V2 can be used for Linux Kernel code (Drivers, Modules, etc) development, it isn¹t really Linux OS aware (CCSV4 did have this feature, but this was dropped in CCSV5). You can see Linux kernel source code, set breakpoints, view global and local variables, but you cannot switch to another kernel process or view many of the kernel data structures. Debugging Kernel Modules is almost impossible. For real Linux Kernel code development I recommend using Lauterbach which is Linux Kernel OS Aware, and takes advantage of the AM335x internal 32k trace buffer, but it is > $5,000.
