[Sony Xperia XZ Premium Accessories] kevinpwhite:
Hello,

I'm currently looking for some USB-C cables and adapters for use with the XZ P with only limited success....

Items which I have found do work with the XZ P are:

USB-C to USB A or uUSB Sync-Charge Cables

Anker USB-C to USB 3.1 Adapter - Short [13cm] (equivalent to 'old' USB2 spec OTG function)

[USB Type C Powerline Specification Gen 1]

Flash Drives - A variety of Flash Drives have been successfully recognised by the XZ P using this adapter and mount as normal storage alongside the built-in uSD card.

Micro SD Card Reader - The Lexar C1 microSD Reader works perfectly.

Hard Disc Drives - I have successfully mounted a Seagate Backup Plus Slim 2 TB USB 3.0 Portable 2.5 inch External Hard Drive using this adapter (formatted as exFAT) together with a Lindy 0.5m USB 3.0 Dual Power Cable, 2 x Type A to Micro-B cable. Power is supplied either from a convenient USB port or a portable power bank. Also a Zalman ZM-VE300 external HDD enclosure fitted with a similar Seagate 2TB 2.5" HDD, also exFAT. FAT32 will also work but only up to 32GB with a 4GB file size limit; NTFS is not recognised.

There does not appear to be any sign of the former manual USB Detection option under Settings, but so far Android seems to just auto-detect, albeit without any apparent notification, which seems a little odd, given the system insists on issuing notifications for everything under the sun otherwise...

>> Update - the OS appears to content itself with a notification labelled "Android System" in the drop-down with the drive name shown. You can then click through to see the drive contents from there or access via Settings | Storage & Memory. <<

Anker USB-C to Micro USB (female) Adapter [2 in 1 Pack]

Boweike USB C to USB 3.0 Retractable Cable

MAPUX USB Type C Cable USB to USB C Cable 3 Pack - Three different lengths - [1 x 30cm, 1 x 90cm + 1 x 180cm]

XGUO® USB Type-C to USB Fast Charge Sync - Short [22cm], Flat cable

[USB Type C Specification Gen 1]

DataPeak USB-C to USB-A 3.0 Cable - Short [20cm], Round cable

[Stated as USB3.0]

This one is pending and will be reported when received/tested:

3 in 1 USB C Type C OTG Charging Host Cable

USB-C to 3.5mm Audio Adapters (with/without Charge-Through option)

The USB-C spec for Audio Adapter Accessory Mode says:

USB-C plug supports analog headsets through an audio adapter accessory with a 3.5 mm socket providing four standard analog audio signals (Left, Right, Mic, and GND). The audio adapter may optionally include a USB-C pass-through plug to allow 500 mA device charging.

But I have had no joy with the following:

Type C USB-C to 3.5mm Audio Jack Adapter, ADTRIP 15cm

Belker Type C to 3.5mm Audio Headphone Stereo Adapter ConnectorDISDIM 2 in 1 Type C to 3.5mm Audio Headphone Jack Adapter with Charger

Motorola Moto Z Connector Type C to 3.5mm Headphone Stereo Adapter Connector

None of these audio adapters seem to be recognised by the phone, either natively or by trying to force a connection using SoundAbout Pro .

It is currently unclear whether Sony have implemented the USB Type C Audio Adapter Accessory Mode (Analogue Audio output) - if anyone has any information on implementation and/or any dongles / software combinations which would facilitate this functionality will be greatly appreciated !

The following uSD Card Reader has also been tried without success:

Rocketek USB C Portable Card Reader for Micro SD Cards

Other Potential Connectivity Members have reported do not work in other posts

- USB-C to Ethernet

- USB-C to HDMI

- USB-C to DisplayPort

- USB-C to VGA

It appears that video-out capability is probably not present, but again, if anyone has any definitive information we can capture it would be useful !

There is a substantial amount of information regarding various USB-C cables collated by Benson Leung of Google on USB-C cables, including an 'approved' list, which incorporates some of those mentioned above.

Best regards,

Kevin
