Error codes may be returned via both the [[../Asm_Interface|assembly language interface]] and the [[../BASIC_Interface|BASIC interface]]. In the BASIC interface, the error code is returned in the first element of the return list. In the assembly language interface, an error is generally indicated by a return with the carry flag set. The error code can then be read from an offset of offErrorCode from the start of the usb8x driver buffer. There may be an additional error code located at offErrorCode+1. Error code equates are located in usb8x.inc.

Error Codes

Error # Name Info
0 OK No error occured
1 Port82 An error occured while waiting for a value from port 82. This generally happens during initialization.
2 Port91Bit2 An error condition was detected via port 91 (NAK?)
3 Port91Bit4 An error condition was detected via port 91 (Stall?)
4 Port4C Port 4C did not hold the expected value. This generally happens during initialization.
5 Port4D Port 4D did not hold the expected value. This generally happens during initialization.
6 Port3A Port 3A did not hold the expected value. This generally happens during initialization.
7 Port81 Port 81 did not hold the expected value. This generally happens during initialization.
8 Port8C The frame counter did not start. This indicates a problem during initialization.
9 Port8F Port 8F did not hold the expected value. This generally happens during initialization.
10 EPIndex A non existant entry point was called. Be sure to check for the minimum required version of usb8x before calling entry points.
11 EPGetDes An unsupported descriptor was requested from [[../Asm_Interface/ReadDescriptor|ReadDescriptor]].
12 NoDevice No Device is connected.
13 FindDescriptor An error occured in [[../Asm_Interface/FindDescriptor|FindDescriptor]].
14 BadClass The attached device does not have the required class. (i.e. a keyboard is connected when [[../Asm_Interface/MouseInit|MouseInit]] is called).
15 Timeout A timeout occured while waiting for data. This currently is only returned by [[../BASIC_Interface/MouseDo|MouseDo]].
16 BadID The attached device does not have the required vendor or device ID.
17 ReadDescriptor An error occured in [[../Asm_Interface/ReadDescriptor|ReadDescriptor]]. Check sub error code for additional information.
18 Init An error occured during initialization. Check sub error code for more information.
19 AutoSetup An error occured during [[../Asm_Interface/AutoSetup|AutoSetup]]. Check sub error code for more information.
20 Demo An error occured in demo code. This should not be returned via either of the programming interfaces.
21 FindPipe An error occured in [[../Asm_Interface/FindPipe|FindPipe]]. This error may occasionally improperly be listed a sub error code, because AutoSetup generates a FindPipe error during normal operation.
22 Stub Returned by stub routines (not current used).
23 GetMaxPacketSize An error occured while trying to determine the maximum supported packet size.
24 SetAddress An error occured while trying to set the device address
25 SendCmd There was a problem sending mass storage I/O commands
26 LargeSect Bytes-per-sector is larger than 512 (not supported)
27 NoParts There were no FAT16 partitions found on the connected mass storage device
28 NoMoreMemory The previous function failed because there is no more free memory (this is a very bad thing)
29 InvalidPartition The FAT16 partition found is invalid because it does not contain 0AA55h
30 NotFile The path passed to a function is to a directory or volume label, not a file
31 NotValidPath The path passed to a function is completely invalid
32 CorruptFile A file is corrupted or otherwise not as expected
33 NotFound File or directory was not found
34 DuplicateFound Duplicate calculator variable was found and not overwritten
35 NotEnoughMem There was not enough memory to create the new calculator variable
36 AlreadyExists An 8x* file of the same name already exists in the current directory
37 StrNotFound String variable from BASIC OpenLib/ExecLib function was not found
38 VarEmpty Variable was empty and transfer was not completed (this is a bad thing; delete new, incomplete file)
39 NoParts32 FAT32 partitions were found, but none were FAT16 (make sure you reformat your drive as FAT16)
