Hi, all, I would like to propose a small patch to chuck, which is just better error handling for write() system calls in util_hid.cpp. I tried to use the EM_log functions instead of fprintf(stder,....). I hope to have used them correctly. I hope to be producing more significant contributions in the near future. Meanwhile, I thought I shouldn't let these little patches accumulate. The attached patch is agains the latest SVN as of this date, and I tested it with gcc 4.6.1 from Ubuntu 11.10 Best regards, Fabbri
