83Plus:Software:usb8x/Error Codes

Error codes may be returned via both the assembly language interface and the 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 via GetErrorCode. Error code equates are located in usb8x.inc.

Error Codes

Error #	Hex	Name	Info
0	00h	OK	No error occurred
1	01h	Port82	The previous command failed or did not terminate. This generally happens during initialization.
2	02h	Port91Bit2	An error condition was detected on an input pipe (Stall)
3	03h	Port91Bit4	An error condition was detected on an input pipe (NAK)
4	04h	Port4C	Port 4C did not hold the expected value. This generally happens during initialization.
5	05h	Port4D	Port 4D did not hold the expected value. This generally happens during initialization.
6	06h	Port3A	Port 3A did not hold the expected value. This generally happens during initialization.
7	07h	Port81	Port 81 did not hold the expected value. This generally happens during initialization.
8	08h	Port8C	The frame counter did not start. This often indicates low batteries.
9	09h	Port8F	Port 8F did not hold the expected value. This generally happens during initialization.
10	0Ah	EPIndex	A non-existent entry point was called. Be sure to check for the minimum required version of usb8x before calling entry points.
11	0Bh	EPGetDes	An unsupported descriptor was requested from ReadDescriptor.
12	0Ch	NoDevice	No Device is connected. You'll get this error if you plug in a mini-B cable instead of mini-A.
13	0Dh	FindDescriptor	An error occurred in FindDescriptor. This error may occasionally improperly be listed a sub error code, because AutoSetup generates a FindDescriptor error during normal operation.
14	0Eh	BadClass	The attached device does not have the required class (i.e. a keyboard is connected when MouseInit is called).
15	0Fh	Timeout	A timeout occurred while waiting for data. This currently is only returned by MouseDo.
16	10h	BadID	The attached device does not have the required vendor or device ID.
17	11h	ReadDescriptor	An error occurred in ReadDescriptor. Check sub error code for additional information.
18	12h	Init	An error occurred during initialization. Check sub error code for more information.
19	13h	AutoSetup	An error occurred during AutoSetup. Check sub error code for more information.
20	14h	Demo	An error occurred in demo code. This should not be returned via either of the programming interfaces.
21	15h	FindPipe	An error occurred in FindPipe.
22	16h	Stub	Returned by stub routines (not current used).
23	17h	GetMaxPacketSize	An error occurred while trying to determine the maximum supported packet size.
24	18h	SetAddress	An error occurred while trying to set the device address
25	19h	SendCmd	There was a problem sending mass storage I/O commands
26	1Ah	LargeSect	Bytes-per-sector is larger than 512 (not supported)
27	1Bh	NoParts	There were no FAT16 partitions found on the connected mass storage device
28	1Ch	NoMoreMemory	The previous function failed because there is no more free memory (this is a very bad thing)
29	1Dh	InvalidPartition	The FAT16 partition found is invalid because it does not contain 0AA55h
30	1Eh	NotFile	The path passed to a function is to a directory or volume label, not a file
31	1Fh	NotValidPath	The path passed to a function is completely invalid
32	20h	CorruptFile	A file is corrupted or otherwise not as expected
33	21h	NotFound	File or directory was not found
34	22h	DuplicateFound	Duplicate calculator variable was found and not overwritten
35	23h	NotEnoughMem	There was not enough memory to create the new calculator variable
36	24h	AlreadyExists	An 8x* file of the same name already exists in the current directory
37	25h	StrNotFound	String variable from BASIC OpenLib/ExecLib function was not found
38	26h	VarEmpty	Variable was empty and transfer was not completed (this is a bad thing; delete new, incomplete file)
39	27h	NoParts32	FAT32 partitions were found, but none were FAT16 (make sure you reformat your drive as FAT16)
40	28h	NoData	There was no data to report. Returned by KBDGetKey
41	29h	Version	A pre-2.30 version of TI-OS is loaded on the calculator.
42	2Ah	BadCmd	A requested command failed. Returned by Vernier driver.
43	2Bh	FeatureDisabled	The feature/driver you tried to call is not compiled into the user's binary.
44	2Ch	FailedCmd	Mass storage command sent successfully and failed to execute. This is bad.
45	2Dh	CmdTimeout	Mass storage command timed out (no response from device at all)
46	2Eh	CmdRefused	All communication attempts were refused (drive has STALLed)
