USB is widely used for charging mobile devices. Using the desktop gaming machine is effective as the full tower has room on top for a wireless charger stand for the iPhone and Apple Watch. The antenna for the WiFi is also placed on top of the tower to get a better signal to improve download speeds.
The wireless stand is not super demanding as it is limited to 5W of charging using Apple hardware. Some new android phones can now use 7.5W of power. Wireless charging has slowly entered the market as patent fights over the technology continue unabated.
BCC 1.2 affords up to 5A of current to handle charging the iPad and Android tablets. Tablets have more room for battery storage which tends to be the standard design.
The older MSI X470-A Gaming Plus supports USB 3.1 so the evolution of USB seems to follow chipsets design. USB 3.2 is standard with the MSI X570-A PRO motherboard which affords enough speed to support video at up to 1920×1080. It is also fast enough for a USB 10GBASE-T adapter.
Some years ago button USB flash sticks found a job on the Canon MB2320 however it is now visible in the network like some older printers in the studio. The MB2320 is wireless so no need to tether it with a USB cable. Years ago printer stands were integrated into desk designs. Now printers are free to be placed anywhere which makes them a much like a departmental class machine. The MB2320 can handle 15,000 pages a month which is 3 boxes of paper. Not many facilities use that much paper.
USB button sticks are mounted on the rear of desktop machines for BIOS updates. The USB stick is also available for BIOS screenshots. Over time the MSI X470-A Gaming Plus has accumulated a huge number of BIOS updates.
The old Xbox 360 controller needs a USB port to connect it. The unit supports the full console peripheral range. The newer Xbox Black Carbon controller is USB-C based for charging rechargeable batteries. USB-C ports are only slowly appearing on PC motherboards and chassis.
Conventional USB stick capacity has grown over time. The largest in the studio at present is 128GB but now 1TB stick are becoming more widely available. Now a USB stick has enough capacity to handle large photo collections which can be safe stored. USB flash sticks can retain data for at least 3-4 years. Old obsolete sticks in the junk box have accumulated. There are now over 100 of them in the box ranging form 64MB and up. Testing the 64MB stick shows it still works which is a testament to a well made product which survived well past technical obsolescence.
1TB capacity is being mass produced and eventually 2TB products may come to the market before long. The VLSI of a memory stick is minimal has it is all arrays of NAND cells. QLC NAND has allowed for higher capacity USB storage. Intel has indicated work on 5 level NAND cells is complete and designs are now being validated which would bump capacity by 25% over existing QLC cells.
On my eBay watch list is a universal 4-way flash memory unit with USB-A, USB-C, Lightning and microUSB for Android. This makes it possible to use the storage with any device on hand. The highest capacity is 1TB which costs about US $30 and comes via air freight so it will only take 10-14 days to surface.
