[javax-usb-devel] Another attempt

[Vasilios Anagnostopoulos]

Dear Roger and javax-usb users . I managed to get the required information with   > "getDescriptor+getConfiguration" >  > bmRequestType 10000000B > bRequest  GET_DESCRIPTOR > wvalue 0x0200 /*Configuration*/ > windex 0 > wvalue  256 bytes (old was only 9 bytes).   It returns 32 bytes , 9 for configuration , 9 for interface and 7+7 for endpoints(which are DATA endpoints) , everything is fine with the specification . The printer is USB1.1   However two problems remain . The first is that HP1000Laserjet does respond to   GET_DEVICE_ID , GET_PORT_STATUS class-specific requests   with   > "getPortStatus" >  > bmRequestType 10100001B > bRequest  0x01 > wvalue 0x0000 /*Configuration*/ > windex 1 or 0 > wvalue 1 byte .   I get a device busy exception . (maybe I do something wrong , so I will keep trying for a while)   The second is that I cannot claim the interface .   Vasileios Anagnostopoulos
