Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command, the initiator usually then issues a SCSI Request Sense command. This process is part of a SCSI protocol called Contingent Allegiance Condition.
Finally the call device.controlTransferOut() will set up the device to communicate through the WebUSB Serial API. Once the set up is all done, data can be transferred to the device using device.transferIn() to transfer bulk data to the device, similarly its sister function device.transferOut() to read data from the device.

0 = Monitor Descriptor (cf. Detailed Timing Descriptor). 2: 0 = reserved 3: Descriptor type. FA–FF currently defined. 00–0F reserved for vendors. 4: 0 = reserved, except for Display Range Limits Descriptor. 5–17: Defined by descriptor type. If text, code page 437 text, terminated (if less than 13 bytes) with LF and padded with SP.
The subclass descriptor is used to declare a device bootable. A boot device meets a minimum adherence to a basic protocol and will be recognized by a computer's BIOS . Each USB HID interface communicates with the host using either a control pipe or an interrupt pipe.
Even CD-ROMs are not handled by all controllers. Device Type is a 5-bit field reported by a SCSI Inquiry Command; defined SCSI Peripheral Device Types include, in addition to many varieties of storage device, printer, scanner, communications device, and a catch-all "processor" type for devices not otherwise listed.
This UART introduces the Auto-RTS and Auto-CTS features in which the RTS# signal is controlled by the UART to signal the external device to stop transmitting when the UART's buffer is full to or beyond a user-set trigger point and to stop transmitting to the device when the device drives the CTS# signal high (logic 0). 16550A
Each key in the registry of Windows NT versions can have an associated security descriptor. The security descriptor contains an access control list (ACL) that describes which user groups or individual users are granted or denied access permissions. The set of registry permissions include 10 rights/permissions which can be explicitly allowed or ...
The KSN is formed from the device's unique identifier, and an internal transaction counter. The (cryptogram, KSN) pair is forwarded on to the intended recipient, typically the merchant acquirer, where it is decrypted and processed further. Internally, the device does the following: Increments the transaction count (using an internal counter)
