Ramps 1.4 usb 2.0 serial driver driver#

I've scoured Google/other forums for any hint as to what might be going on here and cant find anything. I found threads online showing similar issues when using pid autotune but can confirm my printer completes this process for both hotends just fine. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion.

If I set the slicer to only have a single hotend the print completes with no issues with no modifications to the Marlin firmware. RAMPS 1.4 It is a Mega Pololu Shield, or RAMPS for short, designed to fit the entire electronics needed for a RepRap in one small package for low cost. Same issue present on both firmware revisions. I started out on Marlin 1.1.9 and then upgraded to a fresh version of Marlin 2.0 and re-configured form the ground up. Probing the terminal output for both the hotends shows about 14V going to them when heating but when the LED's for both hotends shuts off the voltage goes down to about nothing and the hotends cool due to no power. This same setup/firmware works flawlessly with single hotend printing but as soon as I add the second in the slicer this issue appears. Both PS's are set to 110V as I'm in the US. The hotbed never shows a problem and always gets to temp and stays, its just the hotends that cool. It would fully heat and keep temp for at least a little while longer but would inevitably start to cool once again. I have tried to use both power supplies in tandem by connecting each of the ramps 1.4 12V inputs to each of the power supplies which made the issue a little better. I have both the original Anet A8 PS as well as one purchased from amazon rated at 400W 12V 33A. Initially I thought this might be a problem with the power supply. I do get an error in octoprint showing that the hearterblock failed and a disconnect is issued. When trying to heat both hotends and the hotbed (even just the 2 hotends will produce the same issue just not as quickly) after some time both the hotends will start to cool back down even though the temp is set steady and does not change. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.

Unlike desktop editions, it is not possible to load a driver through an external driver package.

I have an extremely odd issue since I upgraded my very custom 'Anet A8' to dual extruder/hotend. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. I have attached a copy of the temp graph and my config files as well as the error in the terminal output Octoprint connected to the arduino via USB from an rpi 3 b+ First time posting here so please let me know if this would be better served in another part of the forum.Дual exterder (MOTHERBOARD BOARD_RAMPS_14_EEB)
