Hi,

I have a USB Device, which when I connect to the mac
shows only the Vendor Name, and the Product ID of the
Device in System Profiler. It does not show the Vendor
ID. How can I get the Vendor ID for the same ?

Also, can I pass the Vendor Name as well in the
dictionary, when I am trying to do a
IOServiceGetMatchingServices(master_device_port,
matchingDict, &devIter), or should it be only Vendor
ID ?

If you have a USB device attached, you can use the IOServiceMatching call to find the USB device, then ask for the idVendor property. As for the vendor name, IIRC, ASP has a hard-coded table which equates the vendor name with the ID. however, you may find that there is a "USB Vendor Name" property associated with the device, which you can search for. Take a look at the IORegistry page of USBProber to see what properties a specific device has associated with it. -- Sincerely, Rich Kubota email@hidden (408) 974-6212 _______________________________________________ Do not post admin requests to the list.
