Hi Alan, Need your help looking over this detail here. When I run g_mass_storage with stall=0 everything works fine. As soon as I remove it, things go bonkers. Looking at the bulk-only spec, I see: "6.7.2 Hi - Host expects to receive data from the device [ ... ] The specific device requirements are: 1. The device shall receive a CBW. 2. When the CBW is valid and meaningful, then: . The device shall attempt the command. . [Case (6)] If the device intends to send dCBWDataTransferLength, then: The device shall send dCBWDataTransferLength bytes of data. The device shall set bCSWStatus to 00h or 01h. The device shall set dCSWDataResidue to zero. " Case (6) is when Hi == Di, looking at my logs, I have: 720 [ 286.843965] SCSI CDB: 1a 00 3f 00 c0 00 721 [ 286.844000] g_mass_storage gadget: SCSI command: MODE SENSE(6); Dc=6, Di=192; Hc=6, Hi=192 722 [ 286.844018] g_mass_storage gadget: bulk-in set halt 723 [ 286.844034] g_mass_storage gadget: sending command-failure status 724 [ 286.844045] g_mass_storage gadget: sense data: SK x06, ASC x29, ASCQ x00; info x0 Isn't it wrong to halt in this condition ? cheers -- balbi
