+Devices based on Actions Micro/Action Media designs generally use the USB
+VendorID +1de1+, and they can have two operational modes:
+
+ - USB Mass Storage mode (e.g. ProductID: +1101+)
+ - Generic bulk data transfer mode, or Display mode (e.g. ProductID: +c101+)
+
+On recent GNU/Linux systems the switch from Mass Storage mode to Display mode
+is performed automatically by

+manually with the command:
- - USB Mass Storage mode (ProductID: ''1101'')
- - Generic bulk data transfer mode (ProductID: ''c101'')
