hi Darryl

as requested, here is the case with the libusb... here is the output of the command usbrelay-d with libusb, on a Rpi, with 2 x 8 relay boards attached :

./usbrelay -d

I tested with an 8 relay DCCTECH module. No issues like you have seen. I may need to log into your rPi unless you are familiar with gdb. Send an email to xxxx@xxxx and we will organise some keys. sudo usbrelay -d enumerate_relay_boards()Found 1 devices Device Found type: 16c0 05df path: 0003:0009:00 serial_number: HW554 Manufacturer: www.dcttech.com Product: USBRelay8 Release: 100 Interface: 0 Number of Relays = 8 Module_type = 1 HW554_1=0 HW554_2=0 HW554_3=1 HW554_4=0 HW554_5=0 HW554_6=0 HW554_7=0 HW554_8=0

Diagnosis showed that there was a /usr/sbin/usbrelay that was an old version and the subsequent calls to the new libusbrelay.so caused wierdness. Deleted /usr/sbin/usbrelay and pulled the very latest version and rebuilt and reinstalled. Now

usbrelay -d

Thanks you Darryl, this version information was missing. You are right
