Hello! I would like to ask if somebody knows who assigns SDIO vendor IDs? In SDIO Simplified Specification Version 3.00 available from website https://www.sdcard.org/downloads/pls/ in section 16.6 CISTPL_MANFID is: The TPLMID_MANF field identifies the SDIO Card's manufacturer. New codes are assigned by both PCMCIA and JEIDA. The first 256 identifiers (0000h through 00FFh) are reserved for manufacturers who have JEDEC IDs assigned by JEDEC Publication 106. Manufacturers with JEDEC IDs may use their eight-bit JEDEC manufacturer code as the least significant eight bits of their SDIO Card manufacturer code. In this case, the most significant eight bits shall be zero (0). For example, if a JEDEC manufacturer code is 89h, their SDIO Card manufacturer code is 0089h. If a SDIO card manufacturer does not currently have a TPLMID_MANF assigned, one can be obtained at little or no cost from the PCMCIA. So IDs 0x0000 - 0x00FF are assigned by JEDEC 106 and because JEDEC 106 contains one parity bit, it means that only 128-reserved IDs are available for SDIO vendor ids and they were already assigned. This is basically clear and list of these (id, vendor) tuples can be find in JEDEC 106 publication. But who assigns remaining SDIO vendor IDs 0x0100 - 0xFFFF? PCMCIA website http://www.pcmcia.org/ is already down and according to USB-IF press information found in document USB_IF_01212010.pdf from archive https://web.archive.org/web/20160304121938if_/http://www.usb.org/press/USB_IF_01212010.pdf USB-IF acquired PCMCIA assets which probably means also assigning PCMCIA vendor IDs. In archive of www.pcmcia.org is available very old list of vendor IDs: https://web.archive.org/web/20051202104141/http://www.pcmcia.org/tupleid.htm I have tried to find some information about PCMCIA or SDIO vendors and IDs assignment on USB-IF website https://www.usb.org/ but there is absolutely nothing. So has somebody any clue what happened with PCMCIA and its relation with SDIO vendor IDs?
